QCD physics with polarized antiprotons at GSI
P. Lenisa, F. Rathmann, M. Anselmino +17
A polarized antiproton beam at the Facility for Antiproton and Ion Research, proposed by the PAX collaboration, will open a window to new physics uniquely accessible at the new Hig…
CKM Results From CLEO
Karl M. Ecklund
I present recent CLEO measurements of inclusive semileptonic B decay spectra and the branching fraction. I also report preliminary results from a combined fit to spectral moments,…
Pentaquark Search at HERMES
Wolfgang Lorenzon
Evidence for a narrow baryon state at 1528 +- 2.6(stat) +- 2.1(syst) MeV is presented in quasi-real photoproduction on a deuterium target through the decay channel p,K0 to p,pi+,pi…
The HERMES Polarized Hydrogen and Deuterium Gas Target in the HERA Electron Storage Ring
The HERMES Collaboration
The HERMES hydrogen and deuterium nuclear-polarized gas targets have been in use since 1996 with the polarized electron beam of HERA at DESY to study the spin structure of the nucl…
Single-spin asymmetries in semi-inclusive deep-inelastic scattering on a transversely polarized hydrogen target
The HERMES Collaboration
Single-spin asymmetries for semi-inclusive electroproduction of charged pions in deep-inelastic scattering of positrons are measured for the first time with transverse target polar…
Quark helicity distributions in the nucleon for up, down, and strange quarks from semi--inclusive deep--inelastic scattering
HERMES Collaboration, A. Airapetian
Polarized deep--inelastic scattering data on longitudinally polarized hydrogen and deuterium targets have been used to determine double spin asymmetries of cross sections. Inclusiv…
