Higgs decay and CP violation phase in the CPV TNMSSM

In this study, we calculate the Higgs mass matrix and explore the limitations of the minimum conditions of the scalar potential on parameter degrees of freedom in the CP violation TNMSSM. We discuss the contributions of some parameters to Higgs mass, and their impact on the strength of Higgs decay signals in different decay channels \(h\rightarrow \) $h\to$ \(\gamma \gamma \) $\gamma \gamma$ , \(h\rightarrow \) $h\to$ \(VV\) $\mathit{VV}$ \((V=W,Z)\) $(V=W,Z)$ and \(h\rightarrow \) $h\to$ \(f\bar{f}\) $f\overline{f}$ \((f=b,c,\tau )\) $(f=b,c,\tau )$ .
