- Joint with Phenomenology
- A Lattice Calculation of QCD Critical Point from Canonical Ensemble
- Time: 2:30 pm
- Place: 5280 Chamberlin
- Speaker: Keh-Fei Liu, University of Kentucky
- Abstract: At zero chemical potential, the finite temperature transition of QCD is known to be a smooth crossover from lattice simulations. The conjectured first order phase transition and its critical point at finite density is of great theoretical and experimental interest.
I will review the status of the lattice calculation with grand canonical approach and present an algorithm in the canonical approach. The preliminary results on the identification of a first order transition and the determination of the critical point with the help of Maxwell construction will be reported.
