LHC上无希格斯模型中的复合矢量

Composite vectors in Higgless models at the LHC

Antonio Enrique Carcamo Hernandez

摘要:

在强耦合电弱对称性破缺的背景下,属于$SU(2)_{L+R}$伴随表象的质量简并的重矢量复合三重态可能产生于全局$SU(2)_L\times SU(2)_R$对称性下的新的强相互作用不变量,该不变量被自发地破缺为$SU(2)_{L+R}$。假设这些重矢量态之间以及它们与标准模型规范玻色子之间的相互作用用$SU(2)_L\times SU(2)_R/SU(2)_{L+R}$有效手征拉格朗日量描述,在此框架下研究了LHC中矢量玻色子熔合和Drell-Yan湮灭产生的重矢量对.计算了复合矢量衰变到标准模型规范玻色子的同号双轻子和三轻子事件的期望速率。

英文摘要:

In the context of a strongly coupled Electroweak Symmetry Breaking, composite triplet of heavy vectors degenerate in mass belonging to the $SU(2)_{L+R}$ adjoint representation may arise from a new strong interaction invariant under the global $SU(2)_L\times SU(2)_R$ symmetry, which is spontaneously broken down to $SU(2)_{L+R}$. Assuming that the interactions among these heavy vector states and with the Standard Model gauge bosons are described by a $SU(2)_L\times SU(2)_R/SU(2)_{L+R}$ Effective Chiral Lagrangian, the heavy vector pair production at the LHC by Vector Boson Fusion and Drell-Yan annihilation is studied in this framework. The expected rates of same sign di-lepton and tri-lepton events from the decay of the composite vectors into Standard Model gauge bosons are computed.
