phi meson width in the medium from proton induced phi production in nuclei

# metadata.dc.description.abstract[].value
We perform calculations for the production of φ mesons in nuclei at energies just above threshold and study
the A dependence of the cross section. We use results for the φ self-energy in the medium obtained within a chiral
unitary approach. We find a strong A dependence which is tied to the distortion of the incident proton and to the
absorption of the φ on its way out of the nucleus. The effect of this latter process reduces the cross section by
about a factor of 2 in heavy nuclei, proving that the A dependence of the cross section bears valuable information
on the φ width in the nuclear medium. Calculations are done for energies accessible in an experimental facility
like COSY
