The relation between TMDs and PDFs in the covariant parton model approach
A. V. Efremov, P. Schweitzer, O. V. Teryaev +1
We derive relations between transverse momentum dependent distribution functions (TMDs) and the usual parton distribution functions (PDFs) in the 3D covariant parton model, which f…
Images of Quark Intrinsic Motion in Covariant Parton Model
A. V. Efremov, P. Schweitzer, O. V. Teryaev +1
We discuss the relations between TMDs and PDFs in the framework of the covariant parton model. The quark OAM and its connection to TMDs are studied as well.
Quark helicity distributions from longitudinal spin asymmetries in muon-proton and muon-deuteron scattering
COMPASS Collaboration
Double-spin asymmetries for production of charged pions and kaons in semi-inclusive deep-inelastic muon scattering have been measured by the COMPASS experiment at CERN. The data, o…
Azimuthal asymmetries of charged hadrons produced by high-energy muons scattered off longitudinally polarised deuterons
COMPASS Collaboration
Azimuthal asymmetries in semi-inclusive production of positive (h^+) and negative hadrons (h^-) have been measured by scattering 160 GeV muons off longitudinally polarised deuteron…
Measurement of the Collins and Sivers asymmetries on transversely polarised protons
The COMPASS Collaboration, M. G. Alekseev
The Collins and Sivers asymmetries for charged hadrons produced in deeply inelastic scattering on transversely polarised protons have been extracted from the data collected in 2007…
Quark intrinsic motion and the link between TMDs and PDFs in covariant approach
A. V. Efremov, P. Schweitzer, O. V. Teryaev +1
The relations between TMDs and PDFs are obtained from the symmetry requirement: relativistic covariance combined with rotationally symmetric parton motion in the nucleon rest frame…
