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…
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…
Hadron-quark continuity induced by the axial anomaly in dense QCD
N. Yamamoto, T. Hatsuda, M. Tachibana +1
We investigate the interplay between the chiral and diquark condensates on the basis of the Ginzburg-Landau potential with QCD symmetry. We demonstrate that the axial anomaly drive…
