针对不同场景对$e^+ e^-\rightarrow{\tildeχ}_1^0 {\tildeχ}_1^0 h^0$进行完整的单循环校正

Complete One-Loop Corrections to $e^+ e^-\rightarrow{\tildeχ}_1^0 {\tildeχ}_1^0 h^0$ for Different Scenarios

摘要:

本文研究了MSSM中$e^+ e^-$碰撞过程中轻希格斯玻色子($h^0$)与一对最轻中性伴子(${\tildeχ}_1^0$)的辐射修正,包括在环计算中的壳层重整化方案.我们研究了QED修正和弱修正,这两种修正的贡献是显著的,需要在未来的线性对撞机实验中加以考虑。计算结果包括了$e^+ e^-\rightarrow{\tildeχ}_1^0 {\tildeχ}_1^0 h^0$在Higgsino和Gaugino两种不同超对称情况下的数值计算。

英文摘要:

In this work, the radiative corrections to the production of a light Higgs boson ($h^0$) with a pair of lightest neutralinos (${\tildeχ}_1^0$) 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 $e^+ e^-\rightarrow{\tildeχ}_1^0 {\tildeχ}_1^0 h^0$.
