Abstract        :

Minimally doubled fermions are promising techniques to study light quarks on lattice. One of the minimally doubled fermion formulation was proposed by Borici and Creutz. In this talk I will discuss the mixed action lattice QCD with Borici-Creutz valence quarks on staggered sea. 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. The size of unitarity violation due to different discretization of valence and sea quark is determined by measuring $\\\\Delta_{mix}$ and is found to be comparable with other mixed action studies.
