This paper presents results from a next-to-leading order (NLO) calculation of single-top Wt-channel production, interfaced with parton shower Monte Carlo programs using the POWHEG method. The results are compared with those from the MC@NLO method. The implementation of the Wt-channel production process in the POWHEG framework is described, along with the handling of interference effects between NLO corrections and t̄t production. The paper discusses the Born kinematics, virtual and real contributions, and the implementation of the POWHEG method for the Wt-channel process. Results are presented for the Wt-channel production, including comparisons with MC@NLO results and results obtained using the PYTHIA shower. The effects of typical cuts are also discussed. The paper concludes that the POWHEG method provides accurate results for the Wt-channel production, with the difference between DR and DS results serving as a measure of interference effects. The implementation of the POWHEG method is validated by comparing results with MC@NLO and with results obtained using the PYTHIA shower. The paper also discusses the importance of the Wt-channel process in Higgs boson searches and its role as a background in various processes. The results demonstrate that the POWHEG method provides a reliable and accurate description of the Wt-channel production process.This paper presents results from a next-to-leading order (NLO) calculation of single-top Wt-channel production, interfaced with parton shower Monte Carlo programs using the POWHEG method.
