在新的类希格斯标量消失之前学习它

Learning from the New Higgs-like Scalar before It Vanishes

Martin Bauer, Anja Butter, Juan Gonzalez-Fraile, Tilman Plehn, Michael Rauch

摘要:

由ATLAS和CMS观察到的双光子异常的动机,我们开发了一个组合的电弱希格斯扇区的SFitter分析,并在大型强子对撞机的标量门户。理论描述是基于线性有效拉格朗日的希格斯和规范场,结合一个额外的单重标量。关键特征是提取关于组合标量势的门户结构的可靠信息。对于特定的双光子异常,我们发现新的状态很可能形成这样一个希格斯门。为了获得更结论性的结果,我们定义并测试了希格斯玻色子和重标量扇区中威尔逊系数的联系,正如门户设置所建议的那样。

英文摘要:

Motivated by a di-photon anomaly observed by ATLAS and CMS we develop an SFitter analysis for a combined electroweak-Higgs sector, and a scalar portal at the LHC. The theoretical description is based on the linear effective Lagrangian for the Higgs and gauge fields, combined with an additional singlet scalar. The key feature is the extraction of reliable information on the portal structure of the combined scalar potential. For the specific di-photon anomaly we find that the new state might well form such a Higgs portal. To obtain more conclusive results we define and test the connection of the Wilson coefficients in the Higgs and heavy scalar sectors, as suggested by a portal setup.
