Test of phi renormalization in nuclei through phi photoproduction

Abstract

We propose an experimental procedure to find out the medium modifications of the $\varphi$ meson. The reaction is inclusive $\varphi$ photoproduction in nuclei, looking for $K^{+}{K}^{-}$ pairs from the $\varphi$ decay with total momentum smaller than 100-150 $MeV/c$, which are made possible at energies of present laboratories from center of mass $\varphi$ backward production and the help of Fermi motion. We have conducted a many body calculation of the mass distribution of the $\varphi$ adapted to the experimental set up of a recent JLAB experiment where the backwards $\varphi$ photoproduction has been measured. Using recent results for the in medium properties of the $\varphi$, we find that the width of the invariant mass distribution for photoproduction on medium to heavy nuclei is larger than the free $\varphi$ width by a factor of two or more.
