摘要:

本文根据CERN大型强子对撞机(LHC)上希格斯玻色子的发现,考虑在高能$e^+$-$H^0, h^0$直线对撞机上测量最小超对称标准模型(MSSM)中中性希格斯玻色子的三线性耦合。我们确定在LHC观察到的最轻的CP-甚至希格斯玻色子的MSSM的状态。我们实现这个约束,以及所有其他相关的实验约束,在参数空间的MSSM,以研究测量中性希格斯玻色子玻色子的三线性耦合的可行性。对于三线性耦合的测量,我们考虑了多个希格斯粒子的产生过程。我们描绘了MSSM参数空间中中性希格斯玻色子三线性耦合可以在高能正负电子对撞机上测量的区域。

英文摘要:

We consider the measurement of the trilinear couplings of the neutral Higgs bosons~($H^0, h^0$) in the minimal supersymmetric standard model~(MSSM) at a high energy $e^+$ $e^-$ linear collider in the light of the discovery of a Higgs boson at the CERN Large Hadron Collider~(LHC). We identify the state observed at the LHC with the lightest CP-even Higgs boson of the MSSM. We implement this constraint, as well as all the other relevant experimental constraints, on the parameter space of the MSSM in order to study the feasibility of measuring the trilinear couplings of the neutral Higgs bosons. For the measurement of trilinear couplings, we consider the multiple Higgs production processes. We delineate the regions of MSSM parameter space where the trilinear couplings of the neutral Higgs bosons could be measured at a high energy electron-positron collider.
