mass dependence of the topological susceptibility
Julien Frison, Ryuichiro Kitano, Norikazu Yamada
A massless up quark has long been proposed as a solution to the strong CP problem. While this solution is sometimes thought to have been excluded, it is actually still ill-defined.…
Topological susceptibility at high temperature on the lattice
J. Frison, R. Kitano, H. Matsufuru +2
QCD topological susceptibility at high temperature, , provides an important input for the estimate of the axion abundance in the present Universe. While the model independe…
Many flavor approach to study the nature of chiral phase transition of two-flavor QCD
Norikazu Yamada, Shinji Ejiri, Ryo Iwami
We perform lattice numerical simulations to study the phase transition of QCD at finite temperature to clarify the nature of the transition of massless two flavor QCD. We investiga…
Critical point search from an extended parameter space of lattice QCD at finite temperature and density
Shinji Ejiri, Ryo Iwami, Norikazu Yamada
Aiming to understand the phase structure of lattice QCD at nonzero temperature and density, we study the phase transitions of QCD in an extended parameter space, where the number o…
