Chung Kao, Shankar Sachithanandam, Joshua Sayre, Yili Wang

摘要:

我们调查的前景,发现一个中性希格斯玻色子产生一个底夸克,然后希格斯衰变成一对底夸克在欧洲核子研究中心的大型强子对撞机(LHC)和费米实验室Tevatron对撞机。我们在最小超对称标准模型的框架内工作。主要物理学背景是用现实的验收切割和效率计算的,包括$bb\bar{b}$、$\bar{b}b\bar{b}$、$jb\bar{b}$($j = g, q, \bar{q}$ ; $q = u, d, s, c$)、$t\bar{t} \to b\bar{b}jj\ellν$和$t\bar{t} \to b\bar{b}jjjj$的生产。对于CP奇赝标量($A^0$)和较重的CP偶标量($H^0$)希格斯玻色子,在积分光度($L$)为30 fb $^{-1}$和$L =$ 300 fb $^{-1}$的LHC中,其质量可达800 GeV,而在积分光度($L$)为1 TeV时,其质量可达1 TeV。

英文摘要:

We investigate the prospects for the discovery of a neutral Higgs boson produced with one bottom quark followed by Higgs decay into a pair of bottom quarks at the CERN Large Hadron Collider (LHC) and the Fermilab Tevatron Collider. We work within the framework of the minimal supersymmetric standard model. The dominant physics background is calculated with realistic acceptance cuts and efficiencies including the production of $bb\bar{b}$, $\bar{b}b\bar{b}$, $jb\bar{b}$ ($j = g, q, \bar{q}$; $q = u, d, s, c$), $t\bar{t} \to b\bar{b}jj\ellν$, and $t\bar{t} \to b\bar{b}jjjj$. Promising results are found for the CP-odd pseudoscalar ($A^0$) and the heavier CP-even scalar ($H^0$) Higgs bosons with masses up to 800 GeV for the LHC with an integrated luminosity ($L$) of 30 fb$^{-1}$ and up to 1 TeV for $L =$ 300 fb$^{-1}$.
