Chiho Nonaka (HU) Exploring chirality in high-energy heavy-ion collisions

One of the purposes of the high-energy heavy-ion collisions is an investigation of the phase diagram in quantum chromo-dynamics (QCD). Since the strongly coupled quark-gluon plasma (QGP) was discovered at Relativistic Heavy Ion Collider (RHIC), a relativistic hydrodynamic model has been used as description of the space-time evolution of the hot and dense medium produced after the collisions. As the same time, in high-energy heavy-ion collisions, ultraintense electromagnetic fields are produced by the two colliding positively charged nuclei. Furthermore, the fluid of QGP and hadrons is a suitable place to explore chiral property of hadron spectra through invariant mass spectra of lepton pairs. I will start brief introduction of QGP physics. Then I will show our recent progress of chiral mixing on dilepton production and shortly explain construction of a dynamical model for high-energy heavy-ion collision based on the relativistic resistive magneto-hydrodynamic framework.
