Change of θ dependence in 4D SU(N) gauge theories across the deconfinement transition
(2013)We study the dependence of 4D SU(N) gauge theories on the topological θ term at finite temperature T. We exploit the lattice formulation of the theory, presenting numerical results for the expansion of the free energy up ...

Computation of correlation matrices for tetraquark candidates with Jp = 0+ and flavor structure q1q2q3q3
(Proceedings of Science (PoS), 2015)The conjecture that several recently observed mesons have a structure, which is not dominated by an ordinary quark-Antiquark pair, but by a four-quark structure, is being actively investigated both theoretical and ...

Off-equilibrium scaling behaviors across first-order transitions
(2015)We study off-equilibrium behaviors at first-order transitions (FOTs) driven by a time dependence of the temperature across the transition point Tc, such as the linear behavior T(t)/Tc=1±t/ts where ts is a time scale. In ...

Simulating a CP-violating topological term in gauge theories
(2012)We present recent results on the θ-dependence of four-dimensional SU(N) gauge theories, where θ is the coefficient of the CP-violating topological term in the Lagrangian. In particular, we study the scaling behavior of ...
