用么正化有效理论描述2- TeV尺度W_L W_L共振

Describing 2-TeV scale W_L W_L resonances with Unitarized Effective Theory

Felipe J. Llanes-Estrada, Antonio Dobado, Rafael L. Delgado

摘要:

LHC现在正在探索1-3 TeV的尺度,那里可能存在电弱对称性破坏扇区的共振。如果是这样的话,则可以使用么正有效理论来描述具有么正性、因果性和整体对称性破缺的所有约束的数据,并找到复s平面中的共振位置。从发现的任何共振,可以推断出通用的有效拉格朗日的参数,这些参数可以用来通知更高的能量理论(UV完成),可以匹配到it. We与两体共振耦合通道hh和W_L W_L- Z_L Z_L采用等效定理和评论的ATLAS dijet数据在2 TeV的明显过剩。

英文摘要:

The LHC is now exploring the 1-3 TeV scale where resonances of the Electroweak Symmetry Breaking Sector might exist. If so, Unitarized Effective Theory can be used to describe the data with all the constraints of unitarity, causality and global-symmetry breaking, and to find the resonance positions in the complex s-plane. From any resonances found, one can infer the parameters of the universal Effective Lagrangian, and those may be used to inform higher-energy theories (UV completions) that can be matched to it. We exemplify with two-body resonances in the coupled channels hh and W_L W_L- Z_L Z_L employing the Equivalence Theorem and comment on the apparent excess in the ATLAS dijet data at 2 TeV.
