Formation of φ Mesic Nuclei

We consider the structure and formation of the φ mesic nuclei to investigate the experimental feasibility of the observation of signals of the φ mesic nucleus formation. φ mesic nuclei are considered to be very important objects to study the in-medium modification of the φ-meson spectral function at finite density. We consider (¯ p, φ), (γ, p )a nd ( π − ,n )r eactions to produce a φ-meson inside the nucleus and evaluate the effects of its medium modifications to the reaction cross sections. We also estimate the consequences of the uncertainties of the in-medium ¯ K self-energy to the φ-nucleus interaction. We find that it may be possible to see peak structures in the reaction spectra for the strong attractive potential cases. On the other hand, for strong absorptive interaction cases with relatively weak attraction, it is very difficult to observe clear peaks and we may need to know the spectrum shape in a wide energy region to deduce the properties of φ.
