Observation of a Coherence Length Effect in Exclusive Rho^0 Electroproduction

K. Ackerstaff

Exclusive incoherent electroproduction of the rho^0(770) meson from 1H, 2H, 3He, and 14N targets has been studied by the HERMES experiment at squared four-momentum transfer Q**2>0.…

Determination of the Deep Inelastic Contribution to the Generalised Gerasimov-Drell-Hearn Integral for the Proton and Neutron

K. Ackerstaff

The virtual photon absorption cross section differences [sigma_1/2-sigma_3/2] for the proton and neutron have been determined from measurements of polarised cross section asymmetri…

Measurement of the Proton Spin Structure Function g1p with a Pure Hydrogen Target

A. Airapetian

A measurement of the proton spin structure function g1p(x,Q^2) in deep-inelastic scattering is presented. The data were taken with the 27.6 GeV longitudinally polarised positron be…

The Flavor Asymmetry of the Light Quark Sea from Semi-inclusive Deep-inelastic Scattering

K. Ackerstaff

The flavor asymmetry of the light quark sea of the nucleon is determined in the kinematic range 0.02<x<0.3 and 1 GeV^2<Q^2<10 GeV^2, for the first time from semi-inclusive deep-ine…

Beam-Induced Nuclear Depolarisation in a Gaseous Polarised Hydrogen Target

K. Ackerstaff

Spin-polarised atomic hydrogen is used as a gaseous polarised proton target in high energy and nuclear physics experiments operating with internal beams in storage rings. When such…
