چکیده
Coherent ω photoproduction from nuclei and ω properties in nuclear matter. Abstract. The coherent ω-meson photoproduction from nuclei is proposed as a phenomenological method to evaluate the momentum dependence of ω-meson mass shift and width in nuclear matter. We analyze available data on un-separated coherent and incoherent ω-meson photoproduction from nuclei and extract the imaginary part of the the complex forward ωN scattering amplitude, which is proportional to the in-medium ω-meson width. The accuracy of the currently available data is not sufficient to evaluate the real part of forward ωN scattering amplitude and reconstruct the momentum dependence of the mass shift of the ω-meson.

In - Medium properties of the ω meson in photon induced nuclear reactions
We discuss the possibility to study the in-medium changes of the properties of the ω meson in reactions on ordinary nuclei with elementary electromagnetic probes. We present a tree-level calculation of the elementary γp → ωp process which is extended to describe also the photoproduction of medium-modified ω mesons in nuclear matter. Using a semi-classical transport approach we obtain results fo...
متن کاملφ-meson photoproduction from nuclei
We study coherent and incoherent φ-meson photoproduction from nuclei. The available data are analyzed in terms of single and coupled channel photoproduction. It is found that the data on coherent photoproduction can be well reproduced within a single channel optical model and show only little room for ω− φ mixing. These data indicate a normal distortion of the φ-meson in nuclei, which is compat...
متن کاملInclusive ω photoproduction from nuclei and ω in the nuclear medium
With the aim of extracting information on the shift of the ω mass in the nuclear medium we analyze data obtained at ELSA from where claims for evidence of a mass shift of the ω have been made. We develop a Monte Carlo simulation code which takes into account the possible reactions in the experimental set up of (γ A → π0γ X) in the vicinity of the ω production region with subsequent ω → π0γ deca...

We study inclusive ω photoproduction in nuclei and propose a measurement of the nuclear transparency ratio as a means to learn about the in-medium properties of the ω meson. To this end we are using the semi-classical coupled-channel BUU transport approach that allows for a consistent treatment of all nuclear effects. The conditions of our calculations are chosen such as to match the setup of e...
متن کاملPhotoproduction of Quasi-bound Ω Mesons in Nuclei *
We propose the (γ, p) reaction as a means of producing possible quasi-bound states of ω mesons in nuclei. We use an effective Lagrangian, based on chiral SU (3) symmetry and vector meson dominance, in order to construct the ω-nuclear potential. The contribution of bound ω states is observable in the missing energy spectra of protons emitted in forward direction for several nuclei.
