Precision Measurement of the Weak Mixing Angle in Moller Scattering
SLAC E158 Collaboration, P. L. Anthony
We report on a precision measurement of the parity-violating asymmetry in fixed target electron-electron (Moller) scattering: A_PV = -131 +/- 14 (stat.) +/- 10 (syst.) parts per bi…
Exclusive Photoproduction of the Cascade (Xi) Hyperons
J. W. Price
We report on the first measurement of exclusive Xi-(1321) hyperon photoproduction in gamma p --> K+ K+ Xi- for 3.2 < E(gamma) < 3.9 GeV. The final state is identified by the missin…
Exclusive meson electroproduction from hydrogen at CLAS
C. Hadjidakis
The longitudinal and transverse components of the cross section for the reaction were measured in Hall B at Jefferson Laboratory using the CLAS detector. Th…
Observation of an Exotic Baryon in Exclusive Photoproduction from the Deuteron
S. Stepanyan, The CLAS collaboration
In an exclusive measurement of the reaction , a narrow peak that can be attributed to an exotic baryon with strangeness is seen in the invariant m…
Precision Measurement of the Proton and Deuteron Spin Structure Functions g2 and Asymmetries A2
SLAC E155 Collaboration, P. L. Anthony, R. G. Arnold +1
We have measured the spin structure functions g2p and g2d and the virtual photon asymmetries A2p and A2d over the kinematic range 0.02 < x < 0.8 and 0.7 < Q^2 < 20 GeV^2 by scatter…
Next-to-Leading Order QCD Analysis of Polarized Deep Inelastic Scattering Data
The SLAC E154 Collaboration, K. Abe
We present a Next-to-Leading order perturbative QCD analysis of world data on the spin dependent structure functions , and , including the new experimental inf…
