Dileptonic signatures of T-odd quarks at the LHC

TL;DR

This paper investigates how T-odd quarks predicted by Little Higgs models with T-parity could produce distinctive dileptonic signatures at the LHC, aiding in their potential detection.

Contribution

It analyzes the pair production of T-odd quarks and their dileptonic signatures at the LHC, providing insights into their collider phenomenology.

Findings

Opposite-sign dilepton signatures identified as promising signals.

Same-sign dilepton signatures also offer detectable signals.

Results suggest feasible detection strategies for T-odd quarks at the LHC.

Abstract

Little Higgs models are often endowed with a T-parity in order to satisfy electroweak precision tests and give at the same time a stable particle which is a candidate for cold dark matter. This type of models predicts a set of new T-odd fermions in addition to the heavy gauge bosons of the Little Higgs models, which may show interesting signatures at colliders. In this paper, we study the signatures of strong and electroweak pair production of the first two generations of T-odd quarks at the LHC. We focus on the dileptonic signatures (p p to l l j j MET) with (a) opposite-sign dileptons and (b) same-sign dileptons.
