چکیده
We discuss the unexpected enhancement of the N * electroproduc-tion on nuclei recently observed in the (γ * , pπ −) measurement. A mechanism which is able to explain this result is proposed. To clarify the situation, we suggest to perform a new kind of experiment within well specified kinematic conditions. Recently a measurement has been reported [1] of the (γ * , π − p) reaction in the second resonance region (W ≈ 1530 MeV) at different values of the invariant mass W and of the missing momentum p m. This provides valuable information on N * electroproduction and propagation in nuclei. In the same work the data have been compared with theoretical expectations based on a

Coherence Effects in Diffractive Electroproduction of ρ Mesons from Nuclei
A systematic multiple scattering formalism for vector meson electroproduction from nuclei is developed, with emphasis on the formation, propagation and hadronization scales for quark-gluon fluctuations of the virtual high-energy photon. The theory is compared to HERMES measurements of ρ electroproduction on 14 N. The nuclear transparency as a function of the vector meson propagation length is w...
متن کاملFinding Electrostatics modes in Metal Thin Films by using of Quantum Hydrodynamic Model
In this paper, by using a quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, we present the corrected plasmon dispersion relation for graphene which includes a k quantum term arising from the collective electron density wave interference effects (which is integer and constant and k is wave vector). The longitudinal ...

Many of the key issues in understanding quantum chromodynamics involves processes at intermediate energies. We discuss a range of hadronic and nuclear . . _-. phenomena-exclusive processes, color transparency, hidden color degrees of freedom in nuclei, reduced nuclear amplitudes, jet coalescence, formation zone effects, hadron helicity selection rules, spin correlations, higher twist effects, a...

We have studied the electron exchange-correlation effect on thecharacteristics of the two-component unmagnetized dense quantum plasma withstreaming motion. For this purpose, we have used the quantum hydrodynamic model(including the effects of a quantum statistical Fermi electron temperature) for studyingthe propagation of an electrostatic electron plasma waves in such th...
