Differential Cross Sections for gamma + p --> K+ + Y for Lambda and Sigma0 Hyperons
R. Bradford, R. A. Schumacher, J. W. C. McNabb +1
High-statistics cross sections for the reactions gamma + p --> K^+ + Lambda and gamma + p --> K^+ + Sigma^0 have been measured using CLAS at Jefferson Lab for center-of-mass energi…
Sum Rules and Moments of the Nucleon Spin Structure Functions
J. -P. Chen, A. Deur, Zein-Eddine Meziani
The nucleon has been used as a laboratory to investigate its own spin structure and Quantum Chromodynamics. New experimental data on nucleon spin structure at low to intermediate m…
Higher-twist analysis of moments of spin structure function
A. Deur
Available analyses on moments of the spin structure function g_1 use different methods and are barely consistent with each other. We present a higher twist analysis of Gamma_1^p us…
Jefferson Lab's results on the Q^2-evolution of moments of spin structure functions
A. Deur
We present the recent JLab measurements on moments of spin structure functions at intermediate and low Q^2. The Bjorken sum and Burkhardt-Cottingham sum on the neutron are presente…
Measurement of the Polarized Structure Function for Pion Electroproduction in the Roper Resonance Region
CLAS Collaboration, K. Joo, L. C. Smith
The polarized longitudinal-transverse structure function measures the interference between real and imaginary amplitudes in pion electroproduction and can be used t…
Measurement of the Q^2-evolution of the Bjorken integral and extraction of an effective strong coupling constant at low Q^2
A. Deur
We report on the measurement of the Bjorken sum in the range 0.16<Q^2<1.1 GeV^2. The extraction of an effective strong coupling constant is then discussed.
