Measurement of unpolarized semi-inclusive pi+ electroproduction off the proton

CLAS Collaboration, M. Osipenko, M. Ripani +3

Semi-inclusive pi+ electroproduction on protons has been measured with the CLAS detector at Jefferson Lab. The measurement was performed on a liquid-hydrogen target using a 5.75 Ge…

Electroexcitation of the Roper resonance for 1.7 < Q2 < 4.5 GeV2 in ep -> enpi+

I. G. Aznauryan, V. D. Burkert, W. Kim +2

The helicity amplitudes of the electroexcitation of the Roper resonance are extracted for 1.7 < Q2 < 4.5 GeV2 from recent high precision JLab-CLAS cross section and longitudinally…

Polarized Structure Function $σ_{L T^{'}}$ for $p (e, e^{'} K^{+}) Λ$ in the Nucleon Resonance Region

Rakhsha Nasseripour, Brian Raue, Daniel Carman +2

The first measurements of the polarized structure function $σ_{L T^{'}}$ for the reaction $p (e, e^{'} K^{+}) Λ$ in the nucleon resonance region are reported. Measurements are included fro…
