Description
Jets including heavy flavor quarks (HF-jets) are mostly produced from initial hard scattering in relativistic heavy ion collisions. Therefore it is a good probe to study the properties of quark gluon plasma produced from heavy ion collisions. Jets initiating from bottom quarks ($b$-jets) can be identified by the characteristic of b-hadrons such as long lifetime and heavy mass. sPHENIX experiment at Relativistic Heavy Ion Collider is designed for precise measurements of $b$-jets with a MAPS based vertex tracker (MVTX), and the first run is expected to start in 2023. An extensive simulation study has been performed to develop and test $b$-jet tagging algorithms such as secondary vertex method and displaced track counting method. In this poster, simulation studies on $b$-jet tagging algorithms and their performance at sPHENIX will be presented.
