| contents | Two decay channels $h\rightarrow γγ, Zγ$ 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 $h\rightarrow Zγ$ amplitude, but not the $h\rightarrow γγ$ amplitude. From numerical investigations, we show that the signal strength $μ_{Z γ}$ of the decay $h\rightarrow Zγ$ is still constrained strictly by that of $h\rightarrow γγ$, namely $|Δμ_{γγ}|<38\%$ results in max $|Δμ_{Z γ}|<46\%$. On the other hand, the future experimental sensitivity $|Δμ_{γγ}|=4\%$ still allows $|Δμ_{Z γ}|$ reaches to values larger than the expected sensitivity $|Δμ_{Z γ}|=23\%$. |
