论文摘要
希格斯对生产提供了独特的手柄，用于测量希格斯自我相互作用的强度并限制希格斯潜力的形状。包括对$ cp $ - 甚至是希格斯的三线性耦合的辐射校正，我们研究了标准模型的超对称性扩展中，在Gluon融合中最轻的中性希格斯对生产的横截面。数值结果表明，在B-LSSM中，对横截面的校正约为11 \％，而在MSSM中仅为4 \％。考虑到最轻的希格斯实验数据的限制，我们发现$ u（1）_ {b-l} $的量规耦合以及两个单词的非零真空期望值的比率也强烈影响B-LSSM中生产交叉部分的理论评估。
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.
