Production and decay of up-type and down-type new heavy quarks through anomalous interactions at the LHC

TL;DR

This paper investigates the production and decay of hypothetical heavy up- and down-type quarks via anomalous interactions at the LHC, analyzing their signatures and sensitivities at 13 TeV for potential discovery.

Contribution

It presents a detailed analysis of the signatures and sensitivity limits for anomalous couplings of new heavy quarks at the LHC, considering current mass and mixing constraints.

Findings

Sensitivity to anomalous couplings can reach as low as 0.10-0.30 TeV^{-1} for 750 GeV heavy quarks.

Signatures of heavy quark anomalous interactions are identifiable at 13 TeV with 100 fb^{-1} luminosity.

Potential to discover or constrain new heavy quarks through their anomalous interactions at the LHC.

Abstract

We study the process pp->QVX (where Q=t,b and V=g,gamma,Z) through the anomalous interactions of the new heavy quarks at the LHC. Considering the present limits on the masses and mixings, the signatures of the heavy quark anomalous interactions are discussed and analysed at the LHC for the center of mass energy of 13 TeV. An important sensitivity to anomalous couplings kappa_{g}^{t'}/Lambda=0.10 TeV^{-1}, kappa_{\gamma}^{t'}/Lambda=0.14 TeV^{-1}, kappa_{Z}^{t'}/Lambda=0.19 TeV^{-1} and kappa_{g}^{b'}/Lambda=0.15 TeV^{-1}, kappa_{Z}^{b'}/Lambda=0.19 TeV$^{-1}, kappa_{\gamma}^{b'}/Lambda=0.30 TeV$^{-1} for the mass of 750 GeV of the new heavy quarks t' and b' can be reached for an integrated luminosity of L_{int}=100 fb^{-1}.
