Description
There is presently no consensus on how the $\phi$ meson mass and width will
change once it is put in a dense environment such as nuclear matter.
While many theoretical works exist, connecting them with experimental
measurements remains non-trivial task, as the $\phi$ meson in nuclear matter is
usually produced in relatively high-energy pA reactions, which are generally
non-equilibrium processes.
In this presentation, the status of recent theoretical research related to the
behavior of the $\phi$ meson in nuclear matter is reviewed, including works
based on QCD sum rules and ongoing transport simulations of pA reactions
in which the $\phi$ meson is produced in nuclei, focusing on observables that
will be measured at the J-PARC E16 experiment and related recent measurements at ALICE and HADES.
