摘要:

希格斯对的产生为测量希格斯自相互作用的强度和限制希格斯势的形状提供了一个独特的手柄。包括对$CP$ -偶Higgs三线性耦合的辐射修正,我们在超对称扩展的标准模型下研究了大型强子对撞机上胶子聚变产生最轻中性Higgs对的截面.数值结果表明,B-LSSM对截面的修正约为11%,而MSSM仅为4%.考虑到最轻Higgs实验数据的限制,我们发现$U(1)_{B-L}$的规范耦合和两个单态的非零真空期望值之比也强烈影响B-LSSM中产生截面的理论计算.

英文摘要:

Higgs pair production provides a unique handle for measuring the strength of Higgs self interaction and constraining the shape of the Higgs potential. Including radiative corrections to the trilinear couplings of $CP$-even Higgs, we investigate the cross section of the lightest neutral Higgs pair production in gluon fusion at the Large Hadron Collider in the supersymmetric extensions of the standard model. Numerical results indicate that the correction to the cross section is about 11\% in the B-LSSM, while is only about 4\% in the MSSM. Considering the constraints of the experimental data of the lightest Higgs, we find that the gauge couplings of $U(1)_{B-L}$ and the ratio of the nonzero vacuum expectation values of two singlets also affect strongly the theoretical evaluations on the production cross section in the B-LSSM.
