Transverse-momentum resummation at mixed QCD⊗QED NNLL accuracy for Z boson production at hadron colliders

Key Points

• The research focuses on resummation effects in Z boson production at hadron colliders.
• Analyzed transverse momentum distribution of neutral charged bosons.
• Performed resummation of logarithmically-enhanced effects due to QCD and QED radiation.
• Assessed mixed next-to-next-to-leading logarithmic (NNLL) accuracy effects.
• Found percent-level effects from mixed QCD⊗QED resummation.
• Identified impacts on the transverse momentum distribution compared to pure QCD corrections.
