0 Test of φ renormalization in nuclei through φ photoproduction
We propose an experimental procedure to find out the medium modifications of the φ meson. The reaction is inclusive φ photoproduction in nuclei, looking for KK pairs from the φ decay with total momentum smaller than 100-150 MeV/c, which are made possible at energies of present laboratories from center of mass φ backward production and the help of Fermi motion. We have conducted a many body calc...
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 کاملΦ Decay in Nuclei
We have studied the decay of the φ meson in nuclear matter by taking into account the renormalization of the K and K̄ mesons in the medium. We separate the contribution of the total width into different reaction channels, KK̄ and KY h , the latter ones associated with the φN → K+Y reactions. We find a total width at normal nuclear matter density of about 22 MeV, considerably larger than the free ...
متن کاملAutonomous Renormalization of Φ in Finite Geometry
The autonomous renormalization of the O(N)-symmetric scalar theory is based on an infinite re-scaling of constant fields, whereas finite-momentum modes remain finite. The natural framework for a detailed analysis of this method is a system of finite size, where all non-constant modes can be integrated out perturbatively and the constant mode is treated by a saddle-point approximation in the the...
