Mixed action lattice QCD with Borici-Creutz valence quarks on staggered sea is investigated.The counter terms in Borici-Creutz action are fixed nonperturbatively to restore the broken parity and time symmetries. When symmetries are restored, the usual signatures of partial quenching are recovered. We find the scalar correlators to be negative for lower valence quark masses but the errorbars are rather large when their mean values are negative at earlier time slices. The size of unitarity violation due to different discretization of valence and sea quark is determined by measuring ∆ mix and is found to be comparable with other mixed action studies.
