Large Hadron Collider signatures of exotic vector-like quarks within the 2-Higgs doublet model type-II

Key Points

Significant non-standard model decay rates for vector-like quarks X and Y are identifiable.
The study shows evidence of pair production of VLQs, enhancing prospects for detection at the LHC.
The analysis distinguishes between doublet and triplet representations of exotic quarks through unique signatures.
Findings indicate a robust framework within the 2-Higgs doublet model for understanding beyond standard model physics.

Abstract

Abstract We study the decay of the exotic Vector-Like Quarks (VLQs) X and Y, with 5/3 and -4/3 units of electric charge, respectively, within the 2-Higgs Doublet Model (2HDM). Building on our previous studies of Vector-Like Top and Bottom (VLT and VLB) quarks, we now investigate the characteristics of X and Y in the alignment limit of a Type-II Yukawa structure and show that, in the framework of such a 2HDM, one can have large non-Standard Model (SM) decay rates of the X and Y states. Our analysis focuses on their potential detection at the Large Hadron Collider (LHC), based on their pair production followed by a variety of both SM and non-SM decay patterns. In order to distinguish between doublet and triplet representations of the VLQs X and Y, we uncover specific signatures that can provide insights into this particular architecture of Beyond the SM (BSM) physics.
