Transverse-target-spin asymmetry in exclusive -meson electroproduction
The HERMES Collaboration, A. Airapetian, N. Akopov +93
Hard exclusive electroproduction of mesons is studied with the HERMES spectrometer at the DESY laboratory by scattering 27.6 GeV positron and electron beams off a transversely…
Gluons and the quark sea at high energies: distributions, polarization, tomography
D. Boer, M. Diehl, R. Milner +186
This report is based on a ten-week program on "Gluons and the quark sea at high-energies", which took place at the Institute for Nuclear Theory in Seattle in Fall 2010. The princip…
Pentaquark search at HERMES
The HERMES Collaboration, N. Akopov, Z. Akopov +103
The earlier search at HERMES for narrow baryon states excited in quasi-real photoproduction, decaying through the channel , has been extended with impr…
Transverse Momentum Dependent Parton Distribution/Fragmentation Functions at an Electron-Ion Collider
M. Anselmino, H. Avakian, D. Boer +40
We present a summary of a recent workshop held at Duke University on Partonic Transverse Momentum in Hadrons: Quark Spin-Orbit Correlations and Quark-Gluon Interactions. The transv…
Reevaluation of the parton distribution of strange quarks in the nucleon
The HERMES Collaboration, A. Airapetian, N. Akopov +111
An earlier extraction from the HERMES experiment of the polarization-averaged parton distribution of strange quarks in the nucleon has been reevaluated using final data on the mult…
Beam-helicity and beam-charge asymmetries associated with deeply virtual Compton scattering on the unpolarised proton
The HERMES Collaboration, A. Airapetian, N. Akopov +124
Beam-helicity and beam-charge asymmetries in the hard exclusive leptoproduction of real photons from an unpolarised hydrogen target by a 27.6 GeV lepton beam are extracted from the…
