Abstract
We present results of our continuing study on mixed-action hadron spectra and decay constants using overlap valence quarks on MILC’s 2+1+1 flavor HISQ gauge configurations. This study is carried out on three lattice spacings, with charm and strange masses tuned to their physical values, and with ml/ms = 1/5. We present results of an ongoing determination of the mixedaction parameter ∆mix, which enters into chiral formulae for the masses and decay constants.
