Electroproduction 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...

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 twoand three-body interactions with no undetermined parameters. We calculate the S-wave multipoles for threshold production and the deuteron S-wave cross se...

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 ...

Hadronization in Nuclear Environment and Electroproduction of Leading Hadrons∗

Radiative energy loss of a highly virtual quark originating from a deep-inelastic electron scattering plays a crucial role in production of leading hadrons off nuclei. The density of energy loss for gluon radiation turns out to be timeand energy–dependent in inclusive hadron production. Important phenomena involved are Sudakov’s suppression of no radiation of that part of gluon spectrum, which ...
