The Longitudinal Polarimeter at HERA

M. Beckmann, A. Borissov, S. Brauksiepe +12

The design, construction and operation of a Compton back-scattering laser polarimeter at the HERA storage ring at DESY are described. The device measures the longitudinal polarizat…

Measurement of Longitudinal Spin Transfer to Lambda Hyperons in Deep-Inelastic Lepton Scattering

HERMES Collaboration, A. Airapetian

Spin transfer in deep-inelastic Lambda electroproduction has been studied with the HERMES detector using the 27.6 GeV polarized positron beam in the HERA storage ring. For an avera…

Observation of a Single-Spin Azimuthal Asymmetry in Semi-Inclusive Pion Electro-Production

A. Airapetian

Single-spin asymmetries for semi-inclusive pion production in deep-inelastic scattering have been measured for the first time. A significant target-spin asymmetry of the distributi…

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…
