Application of the Subsidiary Fields Method to the Modeling of $$\boldsymbol{tw+t}\bar{\boldsymbol{t}}$$ Processes with the Anomalous $$\boldsymbol{wtb}$$ Interactions
Physics of Atomic Nuclei(2021)
Abstract
Modeling of the pair and single top quark production are discussed in the context of searches for the anomalous $$Wtb$$ couplings. For the simulation of the anomalous $$Wtb$$ couplings in the top quark production and/or decay, the Subsidiary Fields method allows to generate a minimal number of event samples to cover all possible values of the couplings. In the paper the Subsidiary Fields method is applied to simulate the full $$t\bar{t}+tW$$ process with $$tWb$$ final state including the subsequent top quark and $$W$$ boson decays. Correctness of the differential cross sections for arbitrary values of the $$Wtb$$ couplings is demonstrated for the case of the simultaneous presence of the left- and right-handed vector operators in the Wtb vertex.
