在sqrt(s)= 7 TeV的pp碰撞中寻找双电荷希格斯玻色子

A search for a doubly-charged Higgs boson in pp collisions at sqrt(s) = 7 TeV

CMS Collaboration

摘要:

本文提出了在sqrt(s)= 7 TeV pp碰撞中寻找双电荷希格斯玻色子的方法。这些数据对应的积分亮度为4.9个毫微微粒子,由CMS实验在LHC收集。搜索是使用事件与三个或更多个孤立的带电轻子的任何味道,给成对产生的三重态组件的衰变的灵敏度Phi[++]Phi[--],和Phi[++]Phi[-]从相关的生产。与背景预测值相比,未观察到过量,并且在其分支分数的特定假设下,在Phi[++]产生截面上设定了95%置信水平的上限。报告了Phi[++]质量的下限,提供了比以前公布的限制更严格的约束。

英文摘要:

A search for a doubly-charged Higgs boson in pp collisions at sqrt(s) = 7 TeV is presented. The data correspond to an integrated luminosity of 4.9 inverse femtobarns, collected by the CMS experiment at the LHC. The search is performed using events with three or more isolated charged leptons of any flavor, giving sensitivity to the decays of pair-produced triplet components Phi[++]Phi[--], and Phi[++]Phi[-] from associated production. No excess is observed compared to the background prediction, and upper limits at the 95% confidence level are set on the Phi[++] production cross section, under specific assumptions on its branching fractions. Lower bounds on the Phi[++] mass are reported, providing significantly more stringent constraints than previously published limits.
