Asymmetries in phi photoproduction and the OZI violation
read the original abstract
We study the vector meson density matrix and the associated polarization asymmetries in $\phi$ photoproduction near threshold. In order to study the OZI violating processes, we consider the direct $\phi NN$ coupling as well as the knockout processes arising from the non-vanishing $s\bar{s}$ sea quarks in the nucleon. The polarization asymmetries in $\phi$ meson decays are found to be very useful to constrain the $\phi NN$ coupling constant. The hidden strangeness of the nucleon can also be studied by these asymmetries, but mostly at large $|t|$ region.

Polarization-dependent mass modifications of $\phi$ meson with finite momentum in nuclear matter
In nuclear matter, the phi meson's longitudinal polarization mass decreases quadratically with momentum; the transverse polarization mass stays constant.
