Single top and Higgs associated production in the minimal $B-L$ model at the LHC

TL;DR

This paper investigates the production of single top quarks with Higgs bosons in a minimal $B-L$ extension of the Standard Model at the LHC, focusing on cross sections and detection prospects.

Contribution

It provides calculations of production cross sections and analyzes the observability of specific processes in the $U(1)_{B-L}$ model at the LHC.

Findings

Systematic significance can be improved for detection.

Detection remains challenging at 14 TeV LHC with high luminosity.

The study highlights the difficulty in observing these processes.

Abstract

In this paper, we study the single top production in association with a Higgs boson in the $U(1)_{B-L}$ extension of the Standard Model at the LHC. We calculate the production cross sections of the processes $pp\rightarrow thX(h=H_{1},H_{2};X=j,b,W)$ in this model. Then we further study the observability of the process $pp\rightarrow tH_{2}j$ through $pp\rightarrow t(\rightarrow q\bar{q'} b)H_{2}(\rightarrow 4\ell)j$. We find that the systematic significance can be improved obviously, but it is still challenging for the 14 TeV LHC with high-luminosity to detect this signal.
