Abstrakt

We present the implementation of a new interface in vbfnlo 3.0 supporting all diboson and triboson processes with fully leptonic final states, enabling next-to-leading order (NLO)+parton shower (PS) matched calculations. To demonstrate its capabilities, we study parton shower effects in the triboson production process pp→e+νeμ-ν¯μγ+X using herwig 7.3 with NLO QCD amplitudes from vbfnlo 3.0. We estimate uncertainties from scale variations and analyze the impact of generation-level cuts on parton shower events. This study showcases the new interface's potential and provides insights into the interplay between fixed-order calculations and parton shower effects in multiboson production processes, crucial for precision measurements and beyond the Standard Model searches at the LHC and future colliders.
