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 $|\Delta \mu _{\gamma \gamma }|<38\%$ results in max $|\Delta \mu _{Z \gamma }|<46\%$. On the other hand, the future experimental sensitivity $|\Delta \mu _{\gamma \gamma }|=4\%$ still allows |ΔμZγ| reaches to values larger than the expected sensitivity $|\Delta \mu _{Z \gamma }|=23\%$.
期刊介绍:
Progress of Theoretical and Experimental Physics (PTEP) is an international journal that publishes articles on theoretical and experimental physics. PTEP is a fully open access, online-only journal published by the Physical Society of Japan.
PTEP is the successor to Progress of Theoretical Physics (PTP), which terminated in December 2012 and merged into PTEP in January 2013.
PTP was founded in 1946 by Hideki Yukawa, the first Japanese Nobel Laureate. PTEP, the successor journal to PTP, has a broader scope than that of PTP covering both theoretical and experimental physics.
PTEP mainly covers areas including particles and fields, nuclear physics, astrophysics and cosmology, beam physics and instrumentation, and general and mathematical physics.
