sPHENIX Heavy Flavor Physics Simulation Performance

Heavy flavor physics is one of the four main physics programs of the sPHENIX experiment. MVTX is the innermost of the sPHENIX detector that provides excellent position resolution and ultrafast timing resolution to reconstruct secondary vertices of heavy flavor hadron decay. With the precision vertexing performance of MVTX detector and the application of machining algorithm in online trigger and offline analyses, sPHENIX will have excellent capabilities of performing heavy flavor physics measurements. In particular, so far, fully reconstructed b-hadron from exclusive decays has not yet been achieved at RHIC and is crucial to understand the fundamental properties of quark-gluon plasma and heavy quark hadronization mechanisms in different collision systems. In this presentation, We will also report the projected performance of several sPHENIX heavy flavor physics measurements from Mock Data Challenge and discuss the relevant physics.
