φ decay in nuclei Original Research Article

We have studied the decay of the φ meson in nuclear matter by taking into account the renormalization of the K and View the MathML source mesons in the medium. We separate the contribution of the total width into different reaction channels, View the MathML source 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.
