Research Field(Keyword & Summary)
  1. (1) Physics of quarks, gluons and plasma(QGP)

    The purpose of this study is to investigate the thermal equilibrium of high-temperature, high-density nuclear matter produced in high-energy nuclear collisions, based on the saturation picture of gluons.

  2. (2) Direct photon production from QGP

    As a probe of the time evolution of the non-equilibrium state of quarks and gluons, the direct photon method, which is unaffected by the end-state of the reaction, is a promising approach. By calculating the photon production rate along the botom-up-thermailzation scenario and applying the scaling law called geometric scaling, we are trying to reveal the non-equilibrium state.
