Contribution

It provides the first detailed one-loop correction analysis for this process within MSSM, including both QED and weak effects in different SUSY scenarios.

Findings

QED and weak corrections are significant for the process.

Numerical results differ between Higgsino and Gaugino scenarios.

Corrections are essential for accurate predictions in future colliders.

Abstract

In this work, the radiative corrections to the production of a light Higgs boson ($h^0$) with a pair of lightest neutralinos (${\tilde{\chi}}_1^0$) in $e^+ e^-$ collisions within MSSM are presented, including the on-shell renormalization scheme in the loop calculations. We have studied the QED corrections as well as the weak corrections, where the contribution from both corrections is significant and needs to be taken into account in the future linear colliders experiments. The result includes the numerical calculations for two different SUSY scenarios---Higgsino and Gaugino scenarios--- for $e^+ e^-\rightarrow{\tilde{\chi}}_1^0 {\tilde{\chi}}_1^0 h^0$.
