On neutral pion electroproduction off deuterium
Threshold neutral pion electroproduction on the deuteron is studied in the framework of baryon chiral perturbation theory at next–to–leading order in the chiral expansion. To this order in small momenta, the amplitude is finite and a sum of two– and three–body interactions with no undetermined parameters. We calculate the S–wave multipoles for threshold production and the deuteron S–wave cross ...
متن کاملkaon electroproduction off proton
the elementary reaction of kaon exclusive electroproduction on protons has been studied ina broad kinematical range. data for the calculation of the form factor of the kaon have been taken atdifferent values of the invariant center of mass energy w in the range w=1.8, 1.85, 1.98, 2.08 (gev), forone value of the transferred 4-momentum q2=2.35 (gev/c)2. in this analysis, we calculated σl and σt b...
متن کاملStudies of Spin-Orbit Correlations in Kaon Electroproduction in DIS with polarized hydrogen and deuterium targets
We are proposing a comprehensive program to study transverse momentum dependence of valence quark transverse and longitudinal spin distributions through measurements of spin-azimuthal asymmetries in semi-inclusive electroproduction of kaons using the upgraded JLab 11 GeV polarized electron beam and the CLAS12 detector with longitudinally polarized proton and deuteron targets. Main objectives in...

متن کاملElectroproduction of Hadrons from Deuterium
The inclusive electroproduction of hadrons is measured from hydrogen and deuterium targets. The exchanged virtual photons are in the kinematic range -0.25 > cl2 > -3.00 GeV2, 12 <s < 30 GeV2. Hadrons which travel in the direction of the virtual photon in the virtual photon-nucleon center-of-mass system are detected. A striking difference from photoproduction is observed in the excess of positiv...
