Continuum physics with quenched overlap fermions

Abstract

We calculate $m_{ud}=(m_u+m_d)/2$, $m_s$, $f_{\pi }$ and $f_K$ in the quenched continuum limit with UV-filtered overlap fermions. We see rather small scaling violations on lattices as coarse as $a^{-1}\simeq 1\mathrm{GeV}$ and conjecture that similar advantages would be manifest in unquenched studies.
