In J-PARC, possibility of a future heavy-ion program has been discussed. In particular, we discuss heavy ion accelerator schemes, physics goals, and experimental setups. There are two physics subjects included in the program. One is a low energy heavy ion physics, to study unstable nuclei with the linac beam at 1-10 AMeV/c, and the other is a high energy heavy ion physics to explore nuclear physics at a high baryon density with the Main Ring beam at 1-10 AGeV/c. In this work, the latter is presented. In particular, we focus on measurements of lepton pairs in order to study high baryon density, and we also search for exotic hadrons and nuclei. We show a preliminary heavy-ion scheme and design of a heavy ion spectrometer.

The main goals of the J-PARC heavy-ion project are to explore the QCD phase diagram at high baryon density with heavy ions such as uranium at the beam energies of 1-10 AGeV. We are planning to focus on the electron and muon measurements and rare probe search such as multi-strangeness and charmed hadrons by taking advantage of extremely high beam power at J-PARC. A heavy-ion acceleration scheme has been considered with a new heavy-ion linac and a new booster ring, utilizing the existing 3-GeV Rapid-Cycling Synchrotron, and the 50-GeV Main Ring synchrotron.
