Φ Decay in Nuclei
نویسندگان
چکیده
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 one. PACS: 13.15.-k, 13.75.Jz, 14.40.Ev, 25.75.-q

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 کاملMeasuring the φ meson width in the medium from p induced φ production in nuclei
1 Measuring the φ meson width in the medium from p induced φ production in nuclei We study the A dependence of the φ meson production cross section in proton nucleus reactios at energies just above threshold, which are accessible in an experimental facility like COSY. This A dependence has two sources: the distortion of the incident proton and the absorption of the φ in its way out of the nucle...
متن کاملIn-medium Properties of Hadrons – Observables
We first briefly review the theoretical basis for calculations of changes of hadronic properties in dense nuclear matter. These changes have usually been investigated by means of relativistic heavy-ion reactions. Here we discuss that observable consequences of such changes can also be seen in more elementary reactions on nuclei. Particular emphasis is put on a discussion of actual observables i...
متن کاملK − - Nucleus Scattering at Low and Intermediate Energies
We calculate K −-nucleus elastic differential, reaction and total cross sections for different nuclei (12 C, 40 Ca and 208 Pb) at several laboratory antikaon momenta, ranging from 127 MeV (momentum of an antikaon produced in the φ-meson decay) to 800 MeV. We use different antikaon-nucleus optical potentials, some of them fitted to kaonic atom data, and study the sensitivity of the results to th...
