Effective Lagrangian for the ${\chi }_j^{+}{\chi }_k^{-}{H}_l^0$ interaction in the minimal supersymmetric standard model and neutral Higgs decays

Abstract

We extend previous analyses of the supersymmetric loop correction to the neutral Higgs couplings to include the coupling ${\chi }_j^{+}{\chi }_k^{-}{H}_l^0$. The analysis completes the previous analyses where similar corrections were computed for the $\bar{\tau }\tau H_l^0$, $\bar{b}b{H}_l^0$, $\bar{c}c{H}_l^0$ and for $\bar{t}t{H}_l^0$ couplings within the minimal supersymmetric standard model. The effective one loop Lagrangian is then applied to the computation of the neutral Higgs decays. The sizes of the supersymmetric loop corrections of the neutral Higgs decay widths into ${\chi }_i^{+}{\chi }_j^{-}$ ($i=1,2$; $j=1,2$) are investigated and the supersymmetric loop correction is found to be in the range of $7\sim 15$ in significant regions of the parameter space. By including the loop corrections of the other decay channels $\bar{b}b$, $\bar{t}t$, $\bar{\tau }\tau$, $\bar{c}c$, and ${\chi }_i^0{\chi }_j^0$ ($i=1-4$; $j=1-4$), the corrections to branching ratios for $H_l^0\to {\chi }_i^{+}{\chi }_j^{-}$ can reach as high as 40%. The effects of CP phases on the branching ratio are also investigated.
