Summary
This theoretical physics paper provides state-of-the-art predictions for charge asymmetry in W-boson production at the LHC by systematically combining next-to-next-to-leading order QCD corrections with next-to-leading order electroweak radiative corrections using both additive and factorised prescription methods. The analysis demonstrates that electroweak corrections produce sizable effects particularly in forward pseudorapidity regions, with important implications for constraining parton density functions in precision phenomenological studies. The work advocates for explicit inclusion of electroweak corrections in future high-precision experimental measurements.
UK applicability
This paper addresses theoretical particle physics calculations relevant to LHC experiments operated by CERN, in which UK institutions participate. However, the findings have no direct applicability to farming systems, soil health, nutrient density, or human nutritional health—the core domains of Vitagri's Pulse Brain.
Key measures
Lepton charge asymmetry (A_η^l), W-boson charge asymmetry (A_y^W), relative correction factors, K-factors, pseudorapidity (η_l ≤ 4.5), W-boson rapidity (y_W ≤ 4.5)
Outcomes reported
The study presents higher-order theoretical predictions for lepton charge asymmetry in W-boson hadroproduction by combining NNLO QCD with NLO electroweak radiative corrections. The analysis quantifies the magnitude and pseudorapidity dependence of electroweak correction effects on charge asymmetry observables across detector acceptance regions.
