Description

Parton branching solutions of QCD evolution equations have recently been studied
to construct both collinear and transverse momentum dependent (TMD) Parton
distributions. In this formalism, soft-gluon colour coherence effects are taken into account by
introducing the soft-gluon resolution scale. In this talk, we show results of fits to the high precision deep inelastic scattering (DIS) structure function measurements including for the
first time the effects of dynamical, or branching-scale dependent, resolution scales at
Next-to-Leading-Order (NLO) accuracy in the strong coupling
