从实际的2 HDM- II基准到LHC处的$H^\pm \toτν$衰减

From realistic 2HDM-II CPV benchmarks to the $H^\pm \toτν$ decay at the LHC

Lorenzo Basso, Per Osland, Giovanni Marco Pruna

摘要:

本文研究了具有Ⅱ型汤川耦合的CP破坏的双Higgs偶极模型的唯象性质。根据最近的LHC数据,提供了一个更新的可行的参数空间,生存的实验和理论的限制。此外,大型强子对撞机在探索这个模型,通过发现一个带电的希格斯玻色子,在Tauonic模式衰变的范围进行了分析。为此,研究了各种产生通道,重点是玻色子相关通道$gg\to H_i\to H^\pm W^\mp$和费米子相关通道$gb\to H^\pm t$和$gg\to H^\pm bt$。对于后者,进行信号背景分析。

英文摘要:

Phenomenological studies of a CP-violating two-Higgs-doublet Model with type-II Yukawa couplings are presented. In the light of recent LHC data, an update on the viable parameter space that survives both the experimental and theoretical constraints is provided. In addition, the scope of the LHC in exploring this model through the discovery of a charged Higgs boson that decays in the tauonic mode is analysed. For this, various production channels were investigated, with emphasis on the boson-associated channel $gg\to H_i\to H^\pm W^\mp$ and the fermion-associated channels $gb\to H^\pm t$ and $gg\to H^\pm bt$. For the latter, a signal-over-background analysis is performed.
