BSM主要效应:从6维BSM拉格朗日方程得到的完整预测集
BSM Primary Effects: The complete set of predictions from the dimension-6 BSM Lagrangian
摘要:
我们提出了一个物理参数化的领先的影响超出SM(BSM),给我们,目前,最好的方式来限制在低能量的重新物理。我们把这些在维度6水平上限制所有可能相互作用的效应称为BSM初级效应;有8个初级效应与希格斯物理学有关,3个与三重规范耦合有关,7个与LEP的Z极测量有关。从这些实验可测量的变形(而不是运营商),我们构建的6维拉格朗日在自底向上的方式。因此,我们表明,其他BSM效应是不独立的主要的,我们提供了明确的相关性。我们还讨论了在一些动机良好的BSM理论中对这些BSM原色的大小的理论期望。
英文摘要:
We present a physical parameterization of the leading effects beyond the SM (BSM), that give us, at present, the best way to constrain heavy new-physics at low-energies. We call these effects that constrain all possible interactions at the dimension 6 level, BSM Primary effects; there are 8 primaries related to Higgs physics, 3 related to Triple Gauge Couplings and 7 related to Z- pole measurements at LEP. Starting from these experimentally measurable deformations (and not operators), we construct the dimension 6 Lagrangian in a bottom up way. We, thus, show that other BSM effects are not independent from the primary ones and we provide the explicit correlations. We also discuss the theoretical expectation for the size of these BSM primaries in some well-motivated BSM theories.
