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…
Single-spin asymmetries: the Trento conventions
Alessandro Bacchetta, Umberto D'Alesio, Markus Diehl +1
During the workshop "Transversity: New Developments in Nucleon Spin Structure" (ECT*, Trento, Italy, 14-18 June 2004), a series of recommendations was put forward by the participan…
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…
