Unpolarized Transverse Momentum Distributions from a global fit of Drell-Yan and Semi-Inclusive Deep-Inelastic Scattering data
Alessandro Bacchetta, Valerio Bertone, Chiara Bissolotti +5
We present an extraction of unpolarized transverse-momentum-dependent parton distribution and fragmentation functions based on more than two thousands data points from several expe…
T-odd proton-helicity asymmetry in semi-inclusive DIS in perturbative QCD
Maurizio Abele, Matthias Aicher, Fulvio Piacenza +2
We compute the single-spin asymmetry in semi-inclusive deep-inelastic scattering of unpolarized leptons and longitudinally polarized protons at large transverse momentum o…
Transverse-momentum-dependent parton distributions up to NLL from Drell-Yan data
Alessandro Bacchetta, Valerio Bertone, Chiara Bissolotti +4
We present an extraction of unpolarised Transverse-Momentum-Dependent Parton Distribution Functions based on Drell-Yan production data from different experiments, including those a…
Difficulties in the description of Drell-Yan processes at moderate invariant mass and high transverse momentum
Alessandro Bacchetta, Giuseppe Bozzi, Martin Lambertsen +3
We study the Drell-Yan cross section differential with respect to the transverse momentum of the produced lepton pair. We consider data with moderate invariant mass Q of the lepton…
