Double hadron leptoproduction in the nuclear medium
The HERMES Collaboration, A. Airapetian
First measurement of double-hadron production in deep-inelastic scattering has been measured with the HERMES spectrometer at HERA using a 27.6 GeV positron beam with deuterium, nit…
Search for an exotic S=-2, Q=-2 baryon resonance at a mass near 1862 MeV in quasi-real photoproduction
HERMES Collaboration, A. Airapetian
A search for an exotic baryon resonance with has been performed in quasi-real photoproduction on a deuterium target through the decay channel $Ξ^- π^- \to Λπ^- π^- \to…
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,…
Evidence for a narrow |S|=1 baryon state at a mass of 1528 MeV in quasi-real photoproduction
HERMES Collaboration, A. Airapetian
Evidence for a narrow baryon state is found in quasi-real photoproduction on a deuterium target through the decay channel p K^0_S --> p pi^+ pi^-. A peak is observed in the p K^0_S…
Hadron Formation in Deep-Inelastic Positron Scattering in a Nuclear Environment
HERMES Collaboration, A. Airapetian
The influence of the nuclear medium on the production of charged hadrons in semi-inclusive deep-inelastic scattering has been studied by the HERMES experiment at DESY using a 27.5…
Exclusive Leptoproduction of rho^0 Mesons from Hydrogen at Intermediate Virtual Photon Energies
HERMES Collaboration, A. Airapetian
Measurements of the cross section for exclusive virtual-photoproduction of rho^0 mesons from hydrogen are reported. The data were collected by the HERMES experiment using 27.5 GeV…
