Binding effects and nuclear shadowing
The effects of nuclear binding on nuclear structure functions have so far been studied mainly at fixed target experiments, and there is currently much interest in obtaining a clearer understanding of this phenomenon. We use an existing dynamical model of nuclear structure functions, that gives good agreement with current data, to study this effect in a kinematical regime (low x, high Q) that ca...
متن کاملLongitudinal and Transverse Nuclear Shadowing
Nuclear shadowing arises from multiple scattering of the hadronic fluctuations (|qq̄〉, |qq̄g...〉) of the virtual photon in a nucleus. We predict different longitudinal and transverse shadowing and an A–dependence of R ≡ σL/σT which can be up to a 50% effect. The possibility of detecting nuclear effects on R at HERA is discussed. To be published in the Proceedings of the Workshop on “Future Physic...
متن کاملTOPICAL REVIEW Nuclear shadowing
The phenomenon of shadowing of nuclear structure functions at small values of Bjorken-x is analyzed. First, multiple scattering is discussed as the underlying physical mechanism. In this context three different but related approaches are presented: Glauber-like rescatterings, Gribov inelastic shadowing and ideas based on high-density Quantum Chromodynamics. Next, different parametrizations of n...
متن کاملNuclear Shadowing and Rho Photoproduction
Rho photoproduction on complex nuclei is re-examined using a generalised vector dominance model which succesfully predicts the oberved nuclear shadowing in real photoabsorption and deep inelastic scattering. This model is shown to give a good fit to rho photoproduction data on both nucleons and complex nuclei, in which the disagreement between the measured γ − ρ coupling and the γ − ρ coupling ...
متن کاملLeading twist coherent diffraction on nuclei in deep inelastic scattering at small x and nuclear shadowing
We extend the theory of leading twist nuclear shadowing to calculate leading twist nuclear diffractive parton distribution functions (nDPDFs). We observe that the quark and gluon nPDFs have different patterns of the A-dependence. It is found that the probability of diffraction in the quark channel increases with A, reaching about 30% at x ∼ 10−4 for A ∼ 200, and weakly decreases with Q2. In the...
