Single-spin azimuthal asymmetry in exclusive electroproduction of pi^+ mesons

HERMES Collaboration, A. Airapetian

A single-spin asymmetry in the distribution of exclusively produced pi^+ mesons azimuthally around the virtual photon direction relative to the lepton scattering plane has been mea…

Nuclear transparency from quasielastic A(e,e'p) reactions uo to Q^2=8.1 (GeV/c)^2

K. Garrow

The quasielastic (e,ep) reaction was studied on targets of deuterium, carbon, and iron up to a value of momentum transfer of 8.1 (GeV/c). A nuclear transparency…

Measurement of the Beam-Spin Azimuthal Asymmetry Associated with Deeply-Virtual Compton Scattering

HERMES Collaboration, A. Airapetian

The beam-spin asymmetry in hard electroproduction of photons has been measured for the first time. The data have been accumulated by the HERMES experiment at DESY using the HERA 27…

Improved Measurement of the Asymmetry in the Nucleon Sea

NuSea Collaboration, R. S. Towell, P. L. McGaughey

Measurements of the ratio of Drell-Yan yields from an 800 \rm{GeV/c} proton beam incident on liquid hydrogen and deuterium targets are reported. Approximately 360,000 Drell-Yan muo…

Double-Spin Asymmetry in the Cross Section for Exclusive rho^0 Production in Lepton-Proton Scattering

HERMES Collaboration, A. Airapetian

Evidence for a positive longitudinal double-spin asymmetry <A_1^rho> = 0.24 +-0.11 (stat) +-0.02 (syst) in the cross section for exclusive diffractive rho^0(770) vector meson produ…
