Phi decay in nuclei

الأصل · EN

We have studied the decay of the ϕmeson in nuclear matter by taking into account the renormalization of the K and K mesons in the medium. We separate the contribution of the total width into different reaction channels, KK and KYh, 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.
