英文摘要：

A simple method is proposed for determining the masses of new particles in collider events containing a pair of decay chains (not necessarily identical) of the form Z -> Y+1, Y -> X+2, X -> N+3, where 1,2 and 3 are visible but N is not. Initial study of a possible supersymmetric case suggests that the method can determine the four unknown masses in effectively identical chains with good accuracy from samples of a few tens of events.

Coherent helicity amplitude for sequential decays

We present a derivation of coherent helicity amplitudes for a particle decaying into multifinal states with nonzero spins. The results show that the coherent amplitudes introduce additional rotations to transform the helicities into a consistent helicity system, which allows us to add helicity amplitudes for different decay chains coherently. These rotations may have significant effects on the interference between the decay chains in the partial wave analysis.

能量缺失衰变链质量的精确确定

Accurate Mass Determinations in Decay Chains with Missing Energy

许多超越标准模型的理论包括一个稳定的暗物质候选者，它在对撞机探测器中产生丢失/不可见的能量。如果在大型强子对撞机上观察到，我们必须确定它的质量和其他属性（以及它的伙伴）是否预测了正确的暗物质遗迹密度。给出了一种新的测定其质量的方法，误差很小。

Markov Chain Monte Carlo technics applied to Parton Distribution Functions determination: proof of concept

We present a new procedure to determine Parton Distribution Functions (PDFs), based on Markov Chain Monte Carlo (MCMC) methods. The aim of this paper is to show that we can replace the standard $χ^2$ minimization by procedures grounded on Statistical Methods, and on Bayesian inference in particular, thus offering additional insight into the rich field of PDFs determination. After a basic introduction to these technics, we introduce the algorithm we have chosen to implement -- namely Hybrid (or Hamiltonian) Monte Carlo. This algorithm, initially developed for Lattice QCD, turns out to be very i…

利用子系统MT2在强子对撞机上测定能量缺失衰变链的完全质量

Using Subsystem MT2 for Complete Mass Determinations in Decay Chains with Missing Energy at Hadron Colliders

我们建议使用MT 2的概念来测量所有粒子的质量在超对称事件与两个不可观测的，相同的粒子。为此，我们推广了通常的MT 2的概念，并定义了一个新的MT 2（n，p，c）变量，它可以应用于各种子系统拓扑，以及完整的事件拓扑。我们推导出其端点MT 2 {max}（n，p，c）作为未知的测试质量Mc的子链中的最后一个粒子和横向动量pT由于从初始状态的辐射的函数的解析公式。我们证明了端点函数MT 2 {max}（n，p，c）（Mc，pT）可能表现出三种不同类型的扭结，并讨论了每种类型的起源。我们证明，子系统MT 2（n，p，c）变量本身已经产生了足够数量的测量的质谱（包括整体质量尺度）的完整测定。作为一个例子，我们考虑一个简单的情况下，衰变链多达三个重粒子，X2 -> X1 -> X 0，这是相当有问题的所有其他质量测量方法。我们提出了三种不同的基于MT 2的方法，每种方法都可以完全确定粒子X 0，X1和X2的质量。第一种方法仅使用测试质量Mc的单个固定值处的MT 2（n，p，c）端点测量。在第二种方法中，将未知质谱拟合到表现出扭结的一个或多个端点函数MT 2 {max}（n，p，c）（Mc，pT）。第三种方法是混合的，将MT 2端点与不变质量分布中的运动学边缘的测量相结合。作为我们的方法的一个实际应用，我们表明，双轻子W+W-和TT-巴样品在Tevatron可以用于独立的顶夸克，W玻色子和中…

Accurate Mass Determinations in Decay Chains with Missing Energy: II

We discuss kinematic methods for determining the masses of the particles in events at a hadron collider in which a pair of identical particles is produced with each decaying via a series of on-shell intermediate beyond-the-SM (BSM) particles to visible SM particles and an invisible particle (schematically, pp -> ZZ + jets with Z -> Aa -> Bba -> Ccba -> ... -> cba... + N where a,b,c,... are visible SM particles or groups of SM particles, A,B,C,... are on-shell BSM particles and N is invisible). This topology arises in many models including SUSY processes such as squark and gluino pair productio…

On the determination of alpha_s from hadronic tau decays with contour-improved, fixed order and renormalon-chain perturbation theory

One of the largest theoretical uncertainties assigned to the strong coupling constant alpha_s as determined from hadronic tau decays stems from the differences in the results for Fixed Order Perturbation Theory (FOPT), Contour Improved Perturbation Theory (CIPT) and Renormalon Chain Perturbation Theory (RCPT). It is often argued that the three methods differ in the treatment of higher orders only and therefore the full difference should be treated as theoretical error. Recently other arguments either in favor of FOPT, CIPT or RCPT have been given, but none of those is able to combine all three…

Determination of supersymmetric masses using kinematic fits at the LHC

In case of the discovery of supersymmetry at the LHC, the goal will be to identify the underlying theory, its fundamental parameters, and the masses of SUSY particles. We followed here the approach to reconstruct the decay chains in SUSY events under the assumption of common intermediate masses. These masses cannot be extracted from each event because of the unmeasured LSP momenta in case of R-parity conservation. But an ensemble of events can be over-constrained, if the decay chains are long enough, such that enough mass constraints are available. Here, we present a new method combining a) a …

Analysing $j/Ψ$ Production in Various RHIC Interactions with a Version of Sequential Chain Model (SCM)

We have attempted to develop here tentatively a model for $J/Ψ$ production in p+p, d+Au, Cu + Cu and Au + Au collisions at RHIC energies on the basic ansatz that the results of nucleus-nucleus collisions could be arrived at from the nucleon-nucleon (p + p)-interactions with induction of some additional specific features of high energy nuclear collisions. Based on the proposed new and somewhat unfamiliar model, we have tried (i) to capture the properties of invariant $p_T$ -spectra for $J/Ψ$ meson production; (ii) to study the nature of centrality dependence of the $p_T$ -spectra; (iii) to unde…

Improving SUSY Spectrum Determinations at the LHC with Wedgebox Technique

The LHC has the potential not only to discover supersymmetry (SUSY), but also to permit fairly precise measurements of at least a portion of the sparticle spectrum. Proposed mass reconstruction methods rely upon either inverting invariant mass endpoint expressions or upon solving systems of mass-shell equations. These methodologies suffer from the weakness that one certain specific sparticle decay chain is assumed to account for all the events in the sample. Taking two examples of techniques utilizing mass-shell equations, it is found that also applying the wedgebox technique allows for the is…

Three-body decay of $Λ_c^{*} (2765)$ and determination of its spin-parity

We study three-body decays of $Λ_c^{*}(2765) \to Λ_c^+π^+π^-$ by using effective Lagrangians in a non-relativistic framework. We consider the sequential decays through $Σ_c(2455)π$ and $Σ_c^*(2520)π$ in intermediate states which are dominant contributions. The coupling constants in the effective Lagrangians are computed in the quark model. We demonstrate that the ratio $R= Γ(Λ_c^*\toΣ_c^*(2520)π)/Γ(Λ_c^*\to Σ_c(2455)π)$ and angular correlations are sensitive to the spin and parity of $Λ_c^{*}(2765)$. Thus, the measurement of these observables in experimental facilities such as Belle and LHCb c…
