Modeling of processes with anomalous interactions by means of auxiliary fields

Abstract

The paper presents a method of modeling events with anomalous fermionboson couplings by means of an auxiliary vector fields in addition to the SM gauge filed. The method allows to simulate anomalous gauge couplings in different approaches, keeping only the linear order or higher order contributions of the anomalous couplings. The correctness of proposed method is demonstrated by modeling the single top quark production processes with anomalous W tb couplings.
