The study of WH production using different event generators

Abstract

In this paper, we study the process of associated production of the Higgs boson with the W-boson. Signal and background processes are generated using the CompHEP, POWHEG and PYTHIA generators, and the obtained Monte Carlo data is processed in the ROOT program. From this data, in addition to the distributions of the traditional kinematic variables, the distribution for the new angular variables is also obtained. We compared the shape of the distributions of these variables obtained from different generators. It was found that the shape of these distributions is similar for different generators. The deviation of the distributions obtained from POWHEG from other generators can be explained by the fact that it uses NLO correction, but PYTHIA and CompHEP use the LO approximation.
