Abstract.We consider the azimuthal and PT-dependence of hadrons produced in unpolarized Semi-Inclusive Deep Inelastic Scattering (SIDIS) processes, within the factorized QCD parton model. It is shown that at small PT values, PT ≲ 1GeV/c, lowest-order contributions, coupled to unintegrated (transverse-momentum-dependent) quark distribution and fragmentation functions, describe all data. At larger PT values, PT ≳ 1GeV/c, the usual pQCD higher-order collinear contributions dominate. Having… 

Semi-Inclusive Deep Inelastic Scattering: nonperturbative and perturbative regimes

We consider the azimuthal and PT dependence of hadrons produced in unpolarized Semi-Inclusive Deep Inelastic Scattering (SIDIS) processes, within the factorized QCD parton model. It is shown that at

Challenges with large transverse momentum in semi-inclusive deeply inelastic scattering

We survey the current phenomenological status of semi-inclusive deep inelastic scattering at moderate hard scales and in the limit of very large transverse momentum. As the transverse momentum

Mapping the kinematical regimes of semi-inclusive deep inelastic scattering

Abstract We construct a language for identifying kinematical regions of transversely differential semi-inclusive deep inelastic scattering (SIDIS) cross sections with particular underlying

Transverse-momentum-dependent Multiplicities of Charged Hadrons in Muon-Deuteron Deep Inelastic Scattering

A semi-inclusive measurement of charged hadron multiplicities in deep inelastic muon scattering off an isoscalar target was performed using data collected by the COMPASS Collaboration at CERN. The

A Systematic phenomenological study of the cos 2 phi asymmetry in unpolarized semi-inclusive DIS

We study the cos2{phi} azimuthal asymmetry in unpolarized semi-inclusive DIS, taking into account both the perturbative contribution (gluon emission and splitting) and the nonperturbative effects

Perturbative QCD, resummation and non-perturbative aspects in SIDIS processes

Semi-inclusive deep inelastic scattering cross sections, as functions of the transverse momentum qT , are addressed. Soft gluon resummation is performed using the original Collins-Soper-Sterman



Measurement of hadron azimuthal distributions in deep inelastic muon proton scattering

A study of the distribution of the azimuthal angle ϕ of charged hadrons in deep inelastic μ−p scattering is presented. The dependence of the moments of this distribution on the Feynmanx variable and

First measurement of the transverse spin asymmetries of the deuteron in semi-inclusive deep inelastic scattering.

First measurements of the Collins and Sivers asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarized 6LiD target are presented. The data were taken

O(alpha**2(s)) QCD corrections to the electroproduction of hadrons with high transverse momentum

We compute the order {alpha}{sub s}{sup 2} corrections to the one particle inclusive electroproduction cross section of hadrons with nonvanishing transverse momentum. We perform the full calculation

Single-spin asymmetries in semi-inclusive deep-inelastic scattering on a transversely polarized hydrogen target.

Single-spin asymmetries for semi-inclusive electroproduction of charged pions in deep-inelastic scattering of positrons are measured for the first time with transverse target polarization, and the Sivers asymmetry may be affected by exclusive vector meson production.
