论文摘要

我们研究了标准型号Higgs Boson $ h $ H $的异国情调衰变的前景,超出了标准型号标量$ A $,其中包括$ M_ {a} \ Lessim M_ {h}/2 $在单个Higgs中,Higgs和Higgs在HIGHRON Gulluminosity colulider colulider colulider collider collider collider collider collider colulider的高级生产渠道(HLL-LLHC)配对。在HL-LHC上分析了通过异国情调模式$ h \ to AA \至4τ$的HIGGS玻色子衰减的Gluon-Gluon融合和矢量玻色子融合模式中单个HIGGS生产的发现前景。对异国情调的希格斯在非共同希格斯的敏感性中的预计敏感性在hh \ to(h \ to b \ bar {b})(h \ to aa \ to aa \ to aa \ to aa \ to aa \ to aa \ to aa \ to aa \ to aa \ to aa \ to aa \ to a \ to a \ to a \ to a \ to a \ to a \ to aa \ to aa \ to a \ to a \ to a \ to a \ to a \ to a \ to a \ to a \ to a \ to a \ to)上也 估计的。此外,考虑到非共鸣希格斯对生产的污染,我们研究了HL-LHC在$2B4τ$通道中对Higgs-Strahlung工艺的潜在影响力。最后,Hl-lhc在$ \ \ \ {m_ {h {m_ {h}中,探索了Hl-lhc的Hl-lhc $2b4τ$ Channel Pair生产的潜在覆盖范围。我们的研究表明,在几个生产渠道中可以实现对现有界限的重大改进,这激发了HL-LHC和未来千里组的新专门搜索$ h \ rightarrow aa \ rightarrow4τ$。

We study the prospects for observing exotic decays of the Standard Model Higgs boson $h$ into light beyond the Standard Model scalars $a$ with mass $m_{a} \lesssim m_{h}/2$ in the single Higgs and Higgs pair production channels at the high luminosity run of the Large Hadron Collider (HL-LHC). Discovery prospects for single Higgs production in the gluon-gluon fusion and vector boson fusion modes with the Higgs boson decaying via the exotic mode $h \to aa \to 4τ$ are analyzed at the HL-LHC. The projected sensitivity for exotic Higgs decays in the non-resonant Higgs pair production channel $pp \to hh \to (h \to b\bar{b})(h \to aa \to 4τ) \to 2b4τ$ at the HL-LHC and a future $\sqrt{s}=100~$TeV hadron collider (FCC-hh) are also estimated. Furthermore, we study HL-LHC's potential reach for the Higgs-strahlung process in the $2b4τ$ channel, taking into account the contamination from non-resonant Higgs pair production. Finally, the potential reach for resonant Higgs pair production in the $2b4τ$ channel %$pp \to H \to (h \to b\bar{b})(h \to aa \to 4τ)$ at the HL-LHC is also explored for several choices of $\{m_{H},m_{a}\}$. Our studies suggest that significant improvements over existing bounds are achievable in several production channels, motivating new dedicated searches for $h \rightarrow aa \rightarrow 4 τ$ at the HL-LHC and future colliders.
