$ 4τ$衰变通道中NMSSM次轻标量希格斯态的PDKEEPAAA信号

LHC signals of the next-to-lightest scalar Higgs state of the NMSSM in the $ 4τ$ decay channel

摘要:

我们在LHC上研究了NMSSM中次轻CP偶希格斯玻色子$h_2$的$a_1a_1$和$Za_1$衰变通道,其中$h_2$是在胶子聚变中产生的。结果发现,虽然$h_2$的发现是不可能通过后者的通道,前一个在$ 4τ$的最终状态是一个有前途的通道,发现$h_2$与质量高达约250 GeV的大型强子对撞机。这种$h_2$的发现大多伴随着轻$a_1$,这是区分NMSSM和MSSM的明确证据,因为这种轻$a_1$在MSSM中是不可能的。

英文摘要:

We study the $a_1a_1$ and $Za_1$ decay channels of the next-to-lightest CP-even Higgs boson $h_2$ of the NMSSM at the LHC, where the $h_2$ is produced in gluon fusion. It is found that while the $h_2$ discovery is impossible through the latter channel, the former one in the $ 4τ$ final state is a promising channel to discover the $h_2$ with masses up to around 250 GeV at the LHC. Such a discovery of the $h_2$ is mostly accompanied with a light $a_1$, which is a clear evidence for distinguishing the NMSSM from the MSSM since such a light $a_1$ is impossible in the MSSM.
