Description
We revisit the impact of electroweak (EW) radiative corrections on the kinematic distributions of charged leptons in neutrino-induced Charged-Current (CC) Deep Inelastic Scattering (DIS). We implement full Next-to-Leading Order (NLO) EW corrections to CC DIS in a flexible Monte Carlo framework, supplemented with higher-order logarithmically enhanced final-state QED radiation. We compare our results to exclusive NLO QCD plus Parton Shower (PS) predictions obtained with an existing POWHEG-BOX-RES event generator, examining different PS models and settings. Based on this comparison, we provide recommendations for the use of the POWHEG-BOX event generator in experimental analyses. We further assess the impact of radiative corrections on the correlation between the observed muon energy and the incoming neutrino energy for a realistic astrophysical neutrino flux.
These corrections can exceed 10%, yet they are reliably described across several orders of magnitude in energy.
