Search for light gauge boson $Z_{\mu \tau }^{}$ via $t\bar{t}{h}_1^{}$ production at LHC

Jin-Xin Hou, Chong-Xing Yue, Yu-chen Guo

We consider the production of the new gauge boson $Z_{\mu \tau }^{}$ predicted by the ${U(1)}_{L_{\mu }^{}-L_{\tau }^{}}$ model via SM-like Higgs boson $h_1^{}$ decaying in the ${t}\bar{t}h^{}_{…
