摘要:

基本戈德斯通希格斯玻色子(EGH)模型是标准模型(SM)的微扰扩展,它将EGH玻色子确定为观测到的希格斯玻色子。本文研究了在LHC上通过胶子融合产生EGH玻色子对,发现重标量的共振贡献很小,而类SM三角图的贡献被强烈抑制。总产量截面主要来自箱形图的贡献,其值相对于SM预测可显著提高。

英文摘要:

The Elementary Goldstone Higgs (EGH) model is a perturbative extension of the standard model (SM), which identifies the EGH boson as the observed Higgs boson. In this paper, we study pair production of the EGH boson via gluon fusion at the LHC and find that the resonant contribution of the heavy scalar is very small and the SM-like triangle diagram contribution is strongly suppressed. The total production cross section mainly comes from the box diagram contribution and its value can be significantly enhanced with respect to the SM prediction.
