DOI: 10.1007/jhep02(2018)108
Abstract: A bstractWe present an approach to the momentum-space resummation of global, recursively infrared and collinear safe observables that can vanish away from the Sudakov region. We focus on the hadro-production of a generic colour singlet,… read more here.

DOI: 10.1007/jhep02(2025)166
Abstract: We compute the tree-level current for the emission of two soft quark-antiquark pairs in a hard scattering. We also compute the square of this current and discuss the resulting color correlations, featuring dipole correlations and… read more here.

DOI: 10.1103/physrevd.110.096006
Abstract: We complete the perturbative program for equilibrium thermodynamics of cosmological first-order phase transitions of gauge-Higgs theories that map into the (three-dimensional) superrenormalizable SU(2)+doublet effective theory at high temperatures. To this end, we determine their finite-temperature effective… read more here.
