Production and Decay of Up-Type and Down-Type New Heavy Quarks through Anomalous Interactions at the LHC

Abstract

We study the processpp→QV+X(whereQ=t,bandV=g,γ,andZ) 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 couplingsκgt′/Λ=0.10 TeV−1,κγt′/Λ=0.14 TeV−1,κZt′/Λ=0.19 TeV−1andκgb′/Λ=0.15 TeV−1,κZb′/Λ=0.19 TeV−1,κγb′/Λ=0.30 TeV−1for the mass of 750 GeV of the new heavy quarkst′andb′can be reached for an integrated luminosity ofLint=100 fb−1.
