Intrinsic and soft gluons in Monte Carlo event generators

Louis Moureaux, Aleksandra Lelek, Francesco Hautmann +1

Experimental measurements of the transverse momentum of Drell-Yan lepton pairs are sensitive to non-perturbative physics associated with the intrinsic parton transverse momentum $k…

On the PB Sudakov: NNLL coefficient, CS kernel and intrinsic-kt

Aleksandra Lelek

The Transverse Momentum Dependent (TMD) Parton Branching (PB) method incorporates elements of TMD physics into a Monte Carlo (MC) framework to produce high-energy QCD predictions f…

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).…

The small kt-region in Drell-Yan production at next-to-leading order with the Parton Branching Method

I. Bubanja, A. Bermudez Martinez, L. Favart +10

The Parton Branching (PB) method describes the evolution of transverse momentum dependent (TMD) parton distributions, covering all kinematic regions from small to large transverse…

Center-of-mass energy dependence of intrinsic- distributions obtained from Drell-Yan production

I. Bubanja, H. Jung, A. Lelek +2

The internal motion of partons inside hadrons has been studied through its impact on very low transverse momentum spectra of Drell-Yan (DY) pairs created in hadron-hadron collision…
