This report reviews recent progress in fixed-order computations, essential ingredients like parton distribution functions and subtraction methods, and identifies necessary higher-order corrections for Standard Model processes to match anticipated LHC experimental precision, continuing the biennial Les Houches tradition.
This paper generalizes soft and collinear factorization in perturbative QCD to multi-collinear configurations, demonstrating how generalized splitting amplitudes encode the breaking of strict collinear factorization in space-like limits and the failure of naive multiplicative factorization in simultaneous soft-collinear regimes.
This paper summarizes how derivatives of the QCD pressure calculated via lattice QCD are used to construct observables that probe the QCD phase diagram at physical quark masses, specifically analyzing the -flavor chiral phase transition, deconfinement, and the convergence properties of Taylor expansions in the search for the critical endpoint.
This paper calculates enhanced electroweak, QCD, and QED radiative corrections to the nucleon coupling constants and , providing updated relations between lattice-QCD and physical values that yield a total correction of approximately 3.5% to 5.6% and predict a physical axial charge of 1.265(26) or 1.240(9) depending on the input methodology.
This paper presents a physics-informed neural network approach to extract a universal small- dipole scattering amplitude directly from global DIS and photoproduction data without rigid parametric assumptions, successfully resolving the long-standing tension between total and charm cross-section channels while providing a smooth, non-negative input for Color Glass Condensate phenomenology.

This paper improves theoretical predictions for rare -boson decays into heavy vector quarkonium and lepton pairs by including all relevant Standard Model tree-level diagrams, revealing that while fragmentation dominates charmonium channels, additional diagrams increase bottomonium branching fractions by 4–9%, and confirming that forward-backward asymmetries vanish in the Standard Model to provide a baseline for future experimental tests.
