论文摘要
我们研究了光标量与希格斯玻色子和第二代费米子的相互作用,这会触发希格斯玻色子的新罕见衰减成$4μ$,$2μ2γ$,$6μ$和$4μ2J$。我们重铸了当前的LHC搜索以限制这些衰减,并为这些渠道进行新的对撞机分析,而这些渠道仅通过现有研究对这些渠道进行了良好的测试。借助当前收集的数据,我们可以探测小至$ 1.5 \ times10^{ - 5} $,$ 8.7 \ times10^{ - 5} $,$ 5.7 \ times10^{ - 8} $和$ 1.6 \ times10^{ - 7} $。对于集成光度的3 ab $^{ - 1} $的高发光LHC运行,这些数字降至$ 1.3 \ times10^{ - 5} $,$ 2.0 \ times10^{ - 6} $,$ 3.0 \ times10 \ times10 \ times10 \ times10^{ - 9} $ 5.4 \ 5.4 \ times1010^$} $ 9.我们还对仍未开发的其他渠道发表评论。
We investigate the interactions of a light scalar with the Higgs boson and second-generation fermions, which trigger new rare decays of the Higgs boson into $4μ$, $2μ2γ$, $6μ$ and $4μ2j$. We recast current LHC searches to constrain these decays and develop new collider analyses for those channels which are only poorly tested by existing studies. With the currently collected data we can probe branching ratios as small as $1.5 \times10^{-5}$, $8.7 \times10^{-5}$, $5.7 \times10^{-8}$ and $1.6 \times10^{-7}$, respectively. For the High-Luminosity LHC run, considered here to involve 3 ab$^{-1}$ of integrated luminosity, these numbers go down to $1.3 \times10^{-5}$, $2.0 \times10^{-6}$, $3.0 \times10^{-9}$ and $5.4 \times10^{-9}$, respectively. We also comment on other channels that remain still unexplored.
