AI总结:

本文通过新微分方程证明,在特定BSM耦合重求和与区域下,含维度六二导数和维度八四导数算子的有效场论中重标量与矢量场的非退耦效应消失。

摘要:

重标量和矢量场的非退耦效应在LHC上超越标准模型(BSM)物理的间接搜索中扮演重要角色。通过利用1-PI振幅的一些新微分方程,我们证明,在考虑某些BSM耦合的重求和以及相关耦合的特定区域后,对于涉及维度六二导数和维度八四导数算子的一类相当普遍的有效场论,这种非退耦效应是不存在的。

英文摘要:

Non-decoupling effects of heavy scalars and vector fields play an important role in the indirect search of Beyond the Standard Model (BSM) physics at the LHC. By exploiting some new differential equations for the 1-PI amplitudes, we show that such non-decoupling effects are absent for quite a general class of effective field theories involving dimension six two-derivatives and dimension eight four-derivatives operators, once resummation in certain BSM couplings is taken into account and some particular regimes of the relevant couplings are considered.
