meson properties in nuclear matter from dilepton spectra in a transport approachGubler, P.; Bratkovskaya, E.*; Song, T.*
EPJ Web of Conferences, 274, p.07015_1 - 07015_6, 2022/12
There is presently no consensus on how the 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 meson in nuclear matter is usually produced in relatively high-energy pA (p: proton, A: nucleus) reactions, which are generally non-equilibrium processes. In this presentation I will report on an ongoing project, attempting to simulate pA reactions in which the meson is produced in nuclei, making use of a transport approach. Results of simulations of 12 GeV/30 GeV p+C and p+Cu reactions will be presented and comparisons between obtained dilepton spectra and experimental data of the E325 experiment at KEK will be made. Furthermore, predictions for the ongoing J-PARC E16 experiment for both dilepton and 
spectra will be given and discussed.

核物質中の中間子の質量変化は有限密度におけるsクォークのカイラル凝縮の情報を引き出すための重要なプローブであり、J-PARCのE16実験などにおいて実験的に研究されている。しかし、その実験から得られるデータを中間子の質量と結びつけられるために、実際の実験に使う反応の詳細を理解する必要があり、そのためにはトランポートの数値シミュレーションが有用なツールとなる。本講演では、そのトランポートの数値シミュレーションの最近の結果を紹介し、今後の展望について議論する。
