Pion decay constant for the Kogut-Susskind quark action in quenched lattice QCD

JLQCD Collaboration, S. Aoki, M. Fukugita +15

We present a study for the pion decay constant $f_{\pi }$ in the quenched approximation to lattice QCD with the Kogut-Susskind (KS) quark action, with the emphasis given to the renormal…
