Φ in nuclear matter

A general picture of numerous studies in different approaches eg effective Lagrangians and QCD sum rules

- mass modification is small

- main medium effect on the Ф is a significant increase of its width by up to an order of magnitude

To normalize the Φ production cross section we use the known pion data

We present the A-dependence of the Φ production in the following form

The Φ-meson yield (production cross section) follows a target mass

Sum up

model dependent ANKE data analysis suggest

large in-medium Φ-meson width absorption (high momentum part) increasing with momentum

supported by Spring-8 amp JLAB results differential cross sections are not completely reproduced by model calculations (excess at lower momenta) results differ from the Valencia predictions (Φ in-medium self-energy)

Thank you

truncated PW description of ppΦ shows that the contribution from purely S-wave final states represents only a small fraction of the total cross section at ε=76 MeV

explains why there is no S-wave pp-FSI in ANKE amp DISTO data

however in order to explain the energy dependence of the ppΦ total cross section seems to require a low mass Φp enhancement
