Deep-inelastic scattering from off-shell nucleons

Deep-inelastic scattering from off-shell nucleons.

We derive the general structure of the hadronic tensor required to describe deep-inelastic scattering from an off-shell nucleon within a covariant formalism. Of the large number of possible off-shell structure functions we find that only three contribute in the Bjorken limit. In our approach the usual ambiguities encountered when discussing problems related to off-shellness in deep-inelastic sc...

Inelastic Charged - Lepton Scattering off Nucleons * _ Clemens

Particle production from off-shell nucleons

Particle production in equilibrium and nonequilibrium quantum systems is calculated. The effects of the off-shell propagation of nucleons in medium on the particle production are discussed. Comparision to the semiclassical production rate is given. The production of mesons and hard photons in intermediate energy heavy ion collisions is considered to be sensitive to the collision dynamics and to...

Shadowing, binding, and off-shell effects in nuclear deep-inelastic scattering.

We present a unified description of nuclear deep inelastic scattering (DIS) over the whole region 0 < x < 1 of the Bjorken variable. Our approach is based on a relativistically covariant formalism which uses analytical properties of quark correlators. In the laboratory frame it naturally incorporates two mechanisms of DIS: (I) scattering from quarks and antiquarks in the target and (II) product...

Semi-inclusive deep inelastic lepton scattering off complex nuclei

It is shown that in semi-inclusive deep inelastic scattering (DIS) of electrons off a complex nucleus A, the detection, in coincidence with the scattered electron, of a nucleus (A− 1) in the ground state, as well as of a nucleon and a nucleus (A − 2), also in the ground state, may provide unique information on several long standing problems, such as : i) the nature and the relevance of the fina...
