The axial anomaly and the phases of dense QCD
Gordon Baym, Tetsuo Hatsuda, Motoi Tachibana +1
The QCD axial anomaly, by coupling the chiral condensate and BCS pairing fields of quarks in dense matter, leads to a new critical point in the QCD phase diagram \cite{HTYB,chiral2…
Spectral Continuity in Dense QCD
Tetsuo Hatsuda, Motoi Tachibana, Naoki Yamamoto
The vector mesons in three-flavor quark matter with chiral and diquark condensates are studied using the in-medium QCD sum rules. The diquark condensate leads to a mass splitting b…
Thermodynamics and heavy-quark free energies at finite temperature and density with two flavors of improved Wilson quarks
Y. Maezawa, S. Aoki, S. Ejiri +5
Thermodynamics of two-flavor QCD at finite temperature and density is studied on a lattice, using a renormalization group improved gauge action and the clover impro…
Phase structure, collective modes, and the axial anomaly in dense QCD
Naoki Yamamoto, Motoi Tachibana, Tetsuo Hatsuda +1
Using a general Ginzburg-Landau effective Lagrangian, we study the topological structure and low-lying collective modes of dense QCD having both chiral and diquark condensates, for…
Onset of Melting in Quark-Gluon Fluid at RHIC
T. Gunji, H. Hamagaki, T. Hatsuda +1
A strong suppression in central Au+Au collisions has been observed by the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC). We develop a hydro+ model in w…
Bulk and Spectral Observables in Lattice QCD
Tetsuo Hatsuda
We review recent developments in lattice siumulations of the equation of state, order of the thermal phase transition and the determination of the pseudo-critical temperature in (2…
