Description
The lightest Neutralino is a good Dark Matter (DM) candidate
in the R-parity conserving Minimal Supersymmetric Standard Model (MSSM). In this work, we consider light Higgsino-like Neutralino as the Lightest
Stable Particle (LSP), thanks to a relatively small $\mu$ parameter. We then estimate the prominent radiative corrections to the Neutralino-Neutralino-Higgs boson vertices.
We show that these corrections can significantly affect the
spin-independent direct detection cross-section for Higgsino-like Neutralino, even reaching close to 100% in certain regions of the parameter space. These corrections, therefore, play an essential role in deducing constraints on the mass of the Higgsino-like Neutralino Dark Matter and thus the $\mu$ parameter.
