 タイトル: Correlated Dirac eigenvalues and axial anomaly in chiral symmetric QCD
 概要: How axial anomaly manifests itself at the chiral phase transition temperature affects the nature
 of chiral phase transition and it is a fundamental question in QCD. In this talk we present a first
 continuum and chiral extrapolation of two U_A(1) measures in (2+1)-flavor lattice QCD at 1.6T_c. By
 using the proposed novel relations between the quark mass derivatives of Dirac eigenvalue spectrum
 $\rho$ and correlation functions among eigenvalues we find that the peak structure developed in $\rho$
 in the infrared region with its height proportional to quark mass squared is responsible for the current
 manifestation of axial anomaly. These strongly suggest that the axial anomaly is driven by the weakly
 interacting (quasi-)instanton gas motived $\rho$ at T > 1.6T_c and the chiral phase transition belongs
 to 3-d O(4) universality class.
