Associated production of the heavy charged gauge boson $W_H$ and a top quark at LHC

Abstract

In the context of topflavor seesaw model, we study the production of the heavy charged gauge boson $W_H$ associated with a top quark at the LHC. Focusing on the searching channel $pp\to t{W}_H\to t\bar{t}b\to l\nu jjbbb$, we carry out a full simulation of the signal and the relevant standard model backgrounds. The kinematical distributions of final states are presented. It is found that the backgrounds can be significantly suppressed by sets of kinematic cuts, and the signal of the heavy charged boson might be detected at the LHC with $\sqrt{s}=14$ TeV. With a integrated luminosity of $\LL= $ 100 $f{b}^{-1}$, a $8.3\sigma$ signal significance can be achieved for $m_{W_H}=1.6$ TeV.
