Threshold Resummation Effects in Neutral Higgs Boson Production by Bottom Quark Fusion at the CERN Large Hadron Collider

We investigate the QCD effects in the production of neutral Higgs bosons via bottom quark fusion in both the standard model and the minimal supersymmetric standard model at the CERN Large Hadron Collider. We include the next-to-leading order (NLO) QCD corrections (including supersymmetric QCD) and the threshold resummation effects. We use the soft-collinear effective theory to resum the large logarithms near threshold from soft gluon emission. Our results show that the resummation effects can enhance the total cross sections by about 5% compared with the NLO results.

Photoproduction of vector mesons are computed in dipole model in proton-proton ultraperipheral collisions(UPCs) at the CERN Large Hadron Collider (LHC). The dipole model framework is employed in the calculations of vector mesons production in diffractive processes.

Role of parton shadowing in the comparison of p-A and A-A results on jpsi suppression at energies available at the CERN Super Proton Synchrotron

The observation of an anomalous jpsi suppression in nucleus-nucleus collisions is one of the most important results of the SPS heavy-ion program. An essential ingredient in this result is the determination, obtained by studying p-A collisions, of effects not related with the formation of a deconfined medium. These effects are extrapolated to A-A collisions, determining a reference jpsi yield that is then compared with the measurements. In this article we investigate the role of parton shadowing on the determination of such a reference, and we calculate its effect for In-In and Pb-Pb collisions…

Signature of Large Extra Dimensions from Z boson pair production at the CERN Large Hadron Collider

We study the Z boson pair production mediated by the Kaluza-Klein (KK) graviton in large extra dimensions (LED) at the CERN Large Hadron Collider (LHC). We use the partial wave unitarity to discuss the constraints on the process energy scale in order to give a self-consistent calculation. We find that the LED contributions can enhance the Z boson pair production cross sections significantly when the fundamental scale $M_S$ of the large extra dimensions is up to several TeV. We also show that the kinematic distributions of the LED signals are greatly different from the standard model ones and t…

Photoproduction of $ρ^0$ mesons in ultraperipheral heavy ion collisions at energies available at the BNL Relativistic Heavy Ion Collider (RHIC) and CERN Large Hadron Collider (LHC)

Next-to-leading order QCD predictions for $A^{0}γ$ associated production at the CERN Large Hadron Collider

Our results show that the enhancement of the total cross sections from the NLO QCD corrections can reach $15%\sim20%$ for 200 GeV$<m_{A}<500$ GeV and $\tanβ=50$. The scale dependence of the total cross section is improved by the NLO corrections, which is less than 5%. We also show the Monte Carlo simu…

Calculations are done at the energy 5.02 TeV and also for the next LHC run at 8.8 TeV in proton-lead mode. Discussion is performed on the main theoretical uncertainties associated to the calculations.

Technicolor corrections to b\bar{b} -> W^{\pm}π^{\mp}_t at the CERN Large Hadron Collider

In this paper we calculate the technicolor correction to the production of a charged top pion in association with a W boson via b\bar{b} annihilation at the CERN Large Hadron Collider in the context of the topcolor assisted technicolor model. We find that the cross section of pp \rightarrow b\bar{b} -> W^{\pm}π_t^{\mp} at the tree level can reach a few hundred femtobarns for reasonable ranges of the parameters, roughly corresponding to the result of the process pp -> b\bar{b} -> W^{\pm}H^{\mp} in the minimal supersymmetric standard model; the relative corrections arising from the one-loop diag…

Centrality and transverse momentum dependent suppression of $Υ(1S)$ and $Υ(2S)$ in p$-$Pb and Pb$-$Pb collisions at the CERN Large Hadron Collider

Deconfined QCD matter in heavy-ion collisions has been a topic of paramount interest for many years. Quarkonia suppression in heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) experiments indicate the quark-gluon plasma (QGP) formation in such collisions. Recent experiments at LHC has given some indications of hot matter effect in asymmetric p$-$Pb nuclear collisions. Here, we employ a theoretical model to investigate the bottomonium suppression in Pb$-$Pb at $\sqrt{s_{NN}}=2.76$, $5.02$ TeV, and in p$-$Pb at $\sqrt{s_{NN}}=5.02$ TeV center-of-m…

Role of net baryon density on rapidity width of identified particles from the lowest energies available at the CERN Super Proton Synchrotron to those at the BNL Relativistic Heavy Ion Collider and at the CERN Large Hadron Collider

Widths of the rapidity distributions of various identified hadrons generated with the UrQMD-3.4 event generator at all the Super Proton Synchrotron (SPS) energies have been presented and compared with the existing experimental results.

Using MC data, the study has been extended to Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies. A similar jump, as observed in the plot of rapidity width versus rest mass at Alternati…

Colour screening scenario for quarkonia suppression in a quasiparticle model compared with data obtained from experiments at the CERN SPS, BNL RHIC, and CERN LHC

We present a modified colour screening model for $J/ψ$ suppression in the Quark-Gluon Plasma (QGP) using quasi-particle model (QPM) as equation of state (EOS). Other theoretical ingredients incorporated in the model are feed-down from higher resonances namely, $χ_c$, and $ψ^{'}$, dilated formation time for quarkonia and viscous effects of the QGP medium. Assuming further that the QGP is expanding with Bjorken's hydrodynamical expansion, the present model is used to analyze the centrality dependence of the $J/ψ$ suppression in mid-rapidity region and compare it with the data obtained from SPS, …

Bottomonium suppression in PbPb collision at energies available at the CERN large hadron collider

We had been gradually working towards building a comprehensive quarkonia suppression formalism to explain all 3 dependencies of quarkonium suppression obtained from heavy-ion collision experiments. We present here the improved version of quarkonia suppression framework. It assumes bottomonia produced in the early stage which dissociates due to color screening, gluonic dissociation, and collisional damping in addition to the shadowing as an initial state effect. The QGP medium formed in the collisions is assumed to evolve under ($3+1$)-dimensional relativistic viscous hydrodynamics which is mod…

利用b标记增强CERN大型强子对撞机的SUSY范围

Using b-tagging to enhance the SUSY reach of the CERN Large Hadron Collider

假设超对称性是在最小超引力模型（mSUGRA）的双曲分支/焦点（HB/FP）区域中实现的，我们证明了通过寻找多喷流+缺失的E_T事件和标记的b喷流，LHC的实验范围可能比目前的预测扩大20%。这是因为最轻的中性伴子含有大量的希格西诺成分，从而增强了胶子衰变到第三代夸克的过程。虽然我们进行这种分析的动机是因为HB/FP区域与最近确定的冷暗物质的残余密度是一致的，但我们的考虑可能具有更广泛的适用性，因为在各种模型中，胶子衰变为第三代夸克是有利的。

如果下一代重夸克和轻子存在于标准模型（SM）中，它们可以在被实际观察到之前，在Tevatron和LHC中以希格斯玻色子玻色子的形式出现。这一代导致增加的希格斯玻色子生产截面通过胶子融合在强子对撞机的6-9倍。因此，在Tevatron和LHC上对这一过程的研究可以最终确定SM中的代数。使用$WW^*$希格斯玻色子衰变通道，升级后的Tevatron的研究将回答关于质量值为135 GeV $\lsim M_H\lsim 190$ GeV的下一代的问题。通过研究$τ\barτ$通道，我们发现即使在三代的标准情况下，它也具有在大型强子对撞机上研究希格斯玻色子的巨大潜力。在Tevatron，在这个通道中的研究可以探索110-140 GeV的质量范围。

This paper presents the latest development at CERN, concentrating on the status of the LHC and the strategy for future linear colliders. The immediate plans include the exploitation of the LHC at its design luminosity and energy as well as upgrades to the LHC (luminosity and energy) and to its injectors. This may be complemented by a linear electron-positron collider, based on the technology being developed by the Compact Linear Collider and by the International Linear Collider and/or by a high-energy electron-proton collider. This contribution describes the various future directions, all of w…

Neutrino Physics (CERN-2014-001)

I give a theoretical overview of some basic properties of massive neutrinos in these lectures. Particular attention is paid to the origin of neutrino masses, the pattern of lepton flavor mixing, the feature of leptonic CP violation and the electromagnetic properties of massive neutrinos. I highlight the TeV seesaw mechanisms as a possible bridge between neutrino physics and collider physics in the era characterized by the Large Hadron Collider.

Direct Photon Elliptic Flow at BNL Relativistic Heavy Ion Collider (RHIC) and CERN Large Hadron Collider (LHC)

We use an event-by-event hydrodynamical description of the heavy-ion collision process with Glauber initial conditions to calculate the thermal emission of photons. The photon rates in the hadronic phase follow from a spectral function approach and a density expansion, while in the partonic phase they follow from the AMY perturbative rates. The calculated photon elliptic flows are lower than those reported recently by both the ALICE and PHENIX collaborations.

Meson production in two-photon interactions at energies available at CERN Large Hadron Collider

The meson production cross sections are estimated considering photon-photon interactions in hadron - hadron collisions at CERN LHC energies. We consider a large number of mesons with photon-photon partial decay width well constrained by the experiment and some mesons which are currently considered as hadronic molecule and glueball candidates. Our results demonstrate that the experimental analysis of these states is feasible at CERN - LHC.

CERN大型强子对撞机中性希格斯玻色子对产生的次领先阶QCD预言

Next-to-leading order QCD predictions for pair production of neutral Higgs bosons at the CERN Large Hadron Collider

我们在欧洲核子研究中心大型强子对撞机的最小超对称标准模型中计算了中性希格斯玻色子通过$b\bar b$湮灭产生对的完整NLO总截面。在计算中，我们同时使用DREG和DRED两种方案，发现两种方案的非线性光学总截面是相同的。结果表明，当$\tanβ$较大时，对于$h^0H^0$、$A^0h^0$和$A^0H^0$的产生，$b\bar b$湮灭的贡献可以超过$gg$熔合和$q\bar q$湮灭的贡献.在$μ>0$的情况下，非线性光学修正显著地提高了LO总截面，其可以达到百分之几十，而对于$μ<0$，修正相对较小，并且在大多数参数空间中是负的。此外，非线性光学QCD修正可以减少总截面对重整化/因式分解标度的依赖，特别是对$μ<0$。我们还使用CTEQ6.1的PDF集来估计LO和NLO总截面的不确定性，发现PDF的选择所产生的不确定性随着$m_{A^0}$的增加而增加。

CERN大型强子对撞机上的普适双单重态Higgs耦合和唯象

Universal Doublet-Singlet Higgs Couplings and phenomenology at the CERN Large Hadron Collider

我们考虑一个最小的标准模型的扩展，其中一个真正的，规范单标量场被添加到标准谱。引入标量耦合普适性的假设，我们得到了一个具有一组非常独特和可检验的预言的场景：（i）标准模型Higgs和新态之间的混合接近最大值，（ii）两个Higgs质量本征态的比率是固定的（$\sim \sqrt{3}$），（iii）两个本征态中的每一个的衰变模式都是标准模型样的。我们还研究了电弱精度测试如何约束这种情况。我们预测较轻的希格斯粒子在114和145 GeV之间，因此较重的希格斯粒子在198和250 GeV之间。该模型的预测可以在即将到来的LHC上进行测试。

在CERN大型强子对撞机上由电荷-中性子产生的三轻子

Trileptons from Chargino-Neutralino Production at the CERN Large Hadron Collider

我们研究在欧洲核子研究中心大型强子对撞机直接生产电荷和中性伴子。我们使用ISAJET 7.07模拟了电荷伴子和中性伴子产生的所有通道。观察这些过程的最佳模式似乎是$pp\to\tw_1\tz_2\to 3\ell +\eslt$。我们评估信号预期和背景水平，并建议削减以优化信号。如果$m_{\tg}\alt 500-600$ ~GeV，三轻子模式应该是可行的;超过这个质量，$\tz_2\to\tz_1 Z$和$\tz_2\to H_{\ell}\tz_1$衰变模式成为主导，破坏了信号。在第一种情况下，$Z$衰变的轻子分支分数很小，并且存在来自$WZ$的额外背景，而在第二种情况下，三轻子信号基本上不存在。对于较小的$m_{\tg}$值，三轻子信号应该高于背景可见，特别是如果$|μ|\simeq m_{\tg}$和$m_{\tell}\ll m_{\tq}$，在这种情况下，$\tz_2$的轻子衰变增强。由于分布截止点在$m_{\tz_2}-m_{\tz_1}$，双轻子质量分布$m(\ell\bar{\ell})$可以直接给出中性伴子质量的信息。其他的分布，可能会导致一个额外的约束之间的电荷和中性伴子质量也检查。

Single and Double Photonuclear Excitations in Pb+Pb Collisions at sqrt(s_NN) = 2.76 TeV at the CERN Large Hadron Collider

Cross sections are calculated for single and double photon exchange in ultraperipheral Pb+Pb collisions at the LHC. The particle production is simulated with the DPMJET event generator. Large cross sections are found for particle production around mid-rapidity making these processes an important background to hadronic nuclear interactions at both the trigger and analysis levels.

CERN大型强子对撞机MSSM中的相关带电Higgs和W玻色子产生

Associated charged Higgs and W boson production in the MSSM at the CERN Large Hadron Collider

我们研究了在CERN大型强子对撞机上，在最小超对称标准模型（MSSM）的实参数和复参数下，利用轻子衰变H^+ -> tau^+ nu_tau和强子W衰变，观测与W玻色子相关的带电希格斯玻色子（H^+/-）的可行性。执行部分子水平的研究，我们展示了如何从W+2喷流的不可约标准模型背景可以通过应用适当的削减控制，并发现一个可能的信号的大小取决于削减需要抑制QCD背景和错误识别。在MSSM的标准最大混合场景中，当使用乐观切割时，我们发现大tan（β）和中间H^+/-质量（~m_t）的可行信号，而对于更悲观的切割，我们只发现非常大的tan（β）（>~50）的可行信号。我们还研究了一类特殊的MSSM方案，在重希格斯玻色子玻色子之间具有大的质量分裂，其中截面可以共振增强高达100倍，并强烈依赖于CP破坏阶段。即使如此，我们发现切割后的信号仍然很小，除了小质量（~< m_t）与乐观的削减。最后，在我们研究的所有场景中，我们只发现了小的CP不对称。
