Low energy onset of nuclear shadowing in photoabsorption
نویسنده
چکیده
The early onset of nuclear shadowing in photoabsorption at low photon energies (∼ 1 GeV) has recently been interpreted as a possible signature of a decrease of the ρ meson mass in nuclei. We show that one can understand this early onset within simple Glauber theory if one takes the negative real part of the ρN scattering amplitudes into account, corresponding to a higher effective mass of the ρ meson in nuclear medium.

Nuclear Shadowing and In-medium Properties of the Ρ
We explain the early onset of shadowing in nuclear photoabsorption within a multiple scattering approach and discuss its relation to in-medium modifications of the ρ 0. The nuclear photoabsorption cross section is known to be shadowed at large energies, i.e. σ γA < Aσ γN. This was at first interpreted as a confirmation of the vector meson dominance (VMD) model, which assumes that the photon mig...
متن کاملNuclear shadowing at low photon energies
We calculate the shadowing effect in nuclear photoabsorption at low photon energies (1-3 GeV) within a multiple scattering approach. We avoid some of the high energy approximations that are usually made in simple Glauber theory like the narrow width and the eikonal approximation. We find that the main contribution to nuclear shadowing at low energies stems from ρ0 mesons with masses well below ...
متن کاملShadowing in the nuclear photoabsorption above the resonance region
A model based on the hadronic fluctuations of the real photon is developed to describe the total photonucleon and photonuclear cross sections in the energy region above the nucleon resonances. The hadronic spectral function of the photon is derived including the finite width of vector-meson resonances and the quark-antiquark continuum. The shadowing effect is evaluated considering the effective...

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 ...
