The Q^2-Dependence of Nuclear Transparency for Exclusive $\rho^0$ Production
Exclusive coherent and incoherent electroproduction of the $\rho^0$ meson from $^1$H and $^{14}$N targets has been studied at the HERMES experiment as a function of coherence length ($l_c$),Expand
Flavor decomposition of the sea quark helicity distributions in the nucleon from semi-inclusive deep-inelastic scattering
Double-spin asymmetries of semi-inclusive cross sections for the production of identified pions and kaons have been measured in deep-inelastic scattering of polarized positrons on a polarizedExpand
Measurement of R=\sigma_L/\sigma_T in Deep-Inelastic Scattering on Nuclei
Cross section ratios for deep-inelastic scattering from $^3$He, $^{14}$N and $^{84}$Kr with respect to $^2$H have been measured by the HERMES collaboration at DESY using a 27.5 GeV positron beam. TheExpand
The time-of-flight technique for the HERMES experiment
Abstract This paper describes the use of the time-of-flight (TOF) technique as a particle identification method for the HERMES experiment. The TOF is measured by two 1 × 4 m 2 scintillationExpand
Double-spin asymmetries in the cross section of $\rho^0$ and $\phi$ production at intermediate energies
Double-spin asymmetries in the cross section of electroproduction of $\rho^0$ and $\phi$ mesons on the proton and deuteron are measured at the HERMES experiment. The photoabsorption asymmetry inExpand
Quark fragmentation to $\pi^{\pm}$, $\pi^{0}$, $K^{\pm}$, $p$ and $\bar{p}$ in the nuclear environment
The influence of the nuclear medium on lepto-production of hadrons was studied in the HERMES experiment at DESY in semi-inclusive deep-inelastic scattering of 27.6 GeV positrons off deuterium,Expand
The $Q^2$-dependence of the generalised Gerasimov-Drell-Hearn integral for the deuteron, proton and neutron
The Gerasimov-Drell-Hearn (GDH) sum rule connects the anomalous contribution to the magnetic moment of the target nucleus with an energy-weighted integral of the difference of the helicity-dependentExpand
Erratum to:"Nuclear Effects on R=\sigma_L/\sigma_T in Deep-Inelastic Scattering"Phys.Lett. B475(2000)386
This erratum revokes the main conclusion of a Letter that reported measurements of cross sections for deep-inelastic scattering (DIS) of leptons on $^3$He and $^{14}$N targets, expressed as ratios ofExpand
