Description

We calculate the Kaon B parameter by using the Wilson type quark.
We adopt the gradient flow method as a non-perturbative renormalization scheme.
The calculation is performed on Nf=2+1 full QCD configuration generated with the Iwasaki gauge action and the non-perturbatively improved clover action.
We adopt a fine lattice spacing a=0.07 (fm).
The ud quark mass is rather heavy with $m_{\pi }/m_{\rho }\simeq 0.63$ while the s quark mass is set to approximately its physical value.
