Soft-gluon coupling and the TMD parton branching Sudakov form factor
A. Bermudez Martinez, F. Hautmann, L. Keersmaekers +4
The evolution of transverse momentum dependent (TMD) distributions in Quantum Chromodynamics (QCD) can be formulated in a parton branching (PB) framework. We show that next-to-next…

Collinear and TMD distributions with dynamical soft-gluon resolution scale
F. Hautmann, L. Keersmaekers, A. Lelek +2
Soft-gluon resolution scales characterize parton branching Monte Carlo implementations of the evolution equations for parton distribution functions in Quantum Chromodynamics (QCD).…

Perturbative RGE systematics in precision observables
Valerio Bertone, Giuseppe Bozzi, Francesco Hautmann
QCD calculations for collider physics make use of perturbative solutions of renormalisation group equations (RGEs). Ambiguities related to these solutions can contribute significan…
