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…
Radiative Effects in Processes of Diffractive Vector Meson Electroproduction
I. Akushevich
The electromagnetic radiative correction to the cross section of the vector meson electroproduction is calculated. Explicit covariant formulae for the observed cross section are ob…
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…
Radiative electroweak effects in deep inelastic scattering of polarized leptons by polarized nucleons
I. V. Akushevich, A. N. Ilyichev, N. M. Shumeiko
The one-loop electroweak radiative correction of the lowest order to lepton current for deep inelastic scattering of longitudinally polarized leptons by polarized nucleons is obtai…
