用ATLAS探测器搜索在sqrt(s)=7 TeV质子-质子碰撞中轻希格斯玻色子衰变产生的WH

Search for WH production with a light Higgs boson decaying to prompt electron-jets in proton-proton collisions at sqrt(s)=7 TeV with the ATLAS detector

ATLAS Collaboration

摘要:

一个搜索进行WH生产与轻希格斯玻色子玻色子衰变到隐藏的扇形粒子,导致集群的准直电子,称为电子喷流。搜索是在2011年收集的2.04 fb-1的数据与ATLAS探测器在大型强子对撞机在质子-质子碰撞在sqrt(s)=7 TeV。观察到一个满足信号选择标准的事件,这与预期的背景率一致。计算了希格斯玻色子玻色子质量在100 GeV ~ 140 GeV范围内随衰变到电子喷注的希格斯玻色子玻色子的WH产生截面和分支比乘积的极限。

英文摘要:

A search is performed for WH production with a light Higgs boson decaying to hidden-sector particles resulting in clusters of collimated electrons, known as electron-jets. The search is performed with 2.04 fb-1 of data collected in 2011 with the ATLAS detector at the LHC in proton-proton collisions at sqrt(s)=7 TeV. One event satisfying the signal selection criteria is observed, which is consistent with the expected background rate. Limits on the product of the WH production cross section and the branching ratio of a Higgs boson decaying to prompt electron-jets are calculated as a function of a Higgs boson mass in the range from 100 GeV to 140 GeV.
