NLO QCD plus parton-shower matched implementation for VBF Higgs plus photon production, with studies showing small shower effects on Higgs observables and larger effects on sub-leading jets.
Implementation of two NLL-accurate dipole showers in Herwig shows that differences in infrared cutoffs produce noticeable effects at the hadron level and affect model tunability.
The paper decomposes two-loop Yang-Mills gluon amplitudes into color structures via trace and structure-constant bases and organizes relations between the resulting partial amplitudes.
Three nonlinear interacting dark energy models with a saturation ('sparseness') scale are constrained against late-time cosmological data, showing mild preference for nonzero sparseness but no decisive improvement over ΛCDM.
Electroweak radiative corrections are essential for accurate collider predictions, with current techniques and progress illustrated through di-boson production, vector-boson scattering, and tri-boson production.
