Is Large?
Ryuichiro Kitano, Norikazu Yamada, Masahito Yamazaki
We study dependence of the vacuum energy for the 4d SU(2) pure Yang-Mills theory by lattice numerical simulations. The response of topological excitations to the smearing proce…
Topological susceptibility with a single light quark flavour
Julien Frison, Ryuichiro Kitano, Norikazu Yamada
One of the historical suggestions to tackle the strong CP problem is to take the up quark mass to zero while keeping finite. The angle is then supposed to become irreleva…
in gauge theories
Ryuichiro Kitano, Takao Suyama, Norikazu Yamada
In gauge theory, it is argued recently that there exists a "mixed anomaly" between the CP symmetry and the 1-form symmetry at , and the anomaly matching…
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…
