Decays of Standard Model–Like Higgs Boson h → γγ, Zγ in a Minimal Left-Right Symmetric Model

Abstract Two decay channels h → γγ, Zγ of the Standard Model–like Higgs in a left-right symmetry model are investigated using recent experimental data. We show that there exist one-loop contributions that affect the h → Zγ amplitude, but not the h → γγ amplitude. From numerical investigations, we sh...

description Abstract Two decay channels h → γγ, Zγ of the Standard Model–like Higgs in a left-right symmetry model are investigated using recent experimental data. We show that 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 |Δμγγ|
