| dc.description.abstract | 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 selfenergy 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 in its way out of the nucleus. The effect of this latter process reduces the cross section in about a factor two 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 which are accessible in an experimental facility like COSY. | |
