Extracting phi meson properties in nuclear matter from pA reactionsHYBRID

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 seminar, 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, which will start operating in early 2023.
