Project Description

The transition temperature of the strong-interaction matter, described by the theory of Quantum Chromodynamics (QCD), is one of the fundamental scales within the Standard Model of physics, and tells us about the thermal condition when the Universe transitioned from quark-gluon soup to the nuclear matter present today. Using state-of-the-art lattice QCD computations in this project we propose to determine the transition temperature of strong-interaction matter containing more baryons than antibaryons and, thereby, delineate the phase boundary of baryon-rich QCD matter in the temperature and baryon chemical potential plane. These results will not only enhance our fundamental knowledge about strong-interaction matter but also guide the experimental explorations of the QCD phase diagram, particularly the Beam Energy Scan (BES) program at the Relativistic Heavy Ion Collider (RHIC). Additionally, these lattice QCD calculations will provide many other urgently needed QCD inputs that are essential for dynamical modeling of RHIC’s BES.
