Abstract

We study the

a_{1} a_{1}

and

Z a_{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

4 τ

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.

4 τ衰变通道中NMSSM次轻标量希格斯态的LHC信号

我们研究a 1 a1和Z a 1LHC的NMSSM的次轻CP甚至希格斯玻色子h2的衰变通道，其中h2是在胶子融合中产生的。研究发现，尽管通过后一个信道不可能发现h2，前一个处于4τ终态的通道是发现h2的一个很有前途的通道质量高达250左右 LHC的GeV。H2的这种发现大多伴随着一种曙光a 1，这是区分NMSSM和MSSM的明确证据，因为在MSSM中这种光a1是不可能的。
