$ZH\eta$-vertex: EFT Analysis and the Behavior in the SLH Model

Shi-Ping He, Ying-nan Mao, Chen Zhang +1

We re-analyze the $ZH\eta$-vertex with the form $Z_{\mu }(\eta {\partial }^{\mu }H-H{\partial }^{\mu }\eta )$, where $H$ is the 125 GeV Higgs boson and $\eta$ is an exotic pseudo-axion, based on the effective field…
