Abstract:
Two decay channels h → γγ, Zγ of the Standard Model-like Higgs in a left-right symmetry model are investigated under recent experimental data. We will show there exist one-loop contributions that affect the h → Zγ amplitude, but not the h → γγ amplitude. From numerical investigations, we show that the signal strength μZγ of the decay h → Zγ is still constrained strictly by that of h → γγ, namely $|\Delta \mu _{\gamma \gamma }| & lt;38\%$ results in max $|\Delta \mu _{Z \gamma }| & lt;46\%$. On the other hand, the future experimental sensitivity $|\Delta \mu _{\gamma \gamma }|=4\%$ still allows |ΔμZγ| reaches to values larger than the expected sensitivity $|\Delta \mu _{Z \gamma }|=23\%$.
