LHC上ATLAS Run 2奇尼诺和中性子搜索的统计组合

A statistical combination of ATLAS Run 2 searches for charginos and neutralinos at the LHC

ATLAS Collaboration

AI总结:

本文利用ATLAS探测器139 fb^-1的pp碰撞数据,对多种奇尼诺和中性子搜索通道进行统计组合,将SUSY粒子质量探测范围扩展30-100 GeV,并使95%置信水平截面上限降低15%-40%。

摘要:

使用大型强子对撞机ATLAS探测器在质心能量sqrt{s}=13 TeV下收集的139 fb^-1的pp碰撞数据,对利用各种衰变通道搜索奇尼诺和中性子进行了统计组合。将针对纯wino奇尼诺对产生、纯wino奇尼诺-中性子产生,或通过标准模型W、Z或h玻色子衰变的higgsino产生的搜索进行组合,使产生的SUSY粒子的质量探测范围扩展了30-100 GeV。组合还提高了原始搜索的灵敏度深度,将95%置信水平下的截面上限降低了15%-40%。

英文摘要:

Statistical combinations of searches for charginos and neutralinos using various decay channels are performed using $139\,$fb$^{-1}$ of $pp$ collision data at $\sqrt{s}=13\,$TeV with the ATLAS detector at the Large Hadron Collider. Searches targeting pure-wino chargino pair production, pure-wino chargino-neutralino production, or higgsino production decaying via Standard Model $W$, $Z$, or $h$ bosons are combined to extend the mass reach to the produced SUSY particles by 30-100 GeV. The depth of the sensitivity of the original searches is also improved by the combinations, lowering the 95% CL cross-section upper limits by 15%-40%.
