Utilizing the technique developed so far and the power of a state-of-the-art supercomputer, the properties of QCD (Quantum Chromodynamics)- the fundamental theory of strong interaction are being explored. Chiral symmetry is a key aspect of for understanding QCD dynamics; however, it has often been sacrificed in simulations based on lattice QCD, a discretized version of QCD used for simulations.

In this study, we focus on the QCD thermodynamics, employing a chiral fermion formulation, called domain wall fermions to accurately capture the physics of chiral symmetry and its spontaneous breaking. This approach makes it possible to almost directly see what occurred in the early universe during the creation of the matter (and thus our mass!)

Using snapshots of the results obtained, a discussion will be presented, along with prospects for future studies.
