Λ_c and B⁺ production in Au+Au collision at √s_NN= 200 GeV at sPHENIX

Recent results from RHIC and LHC show that nuclear modification factor and elliptic flow of open charm hadrons are similar to those of light flavor hadrons. Furthermore, a strong enhancement of Λ_c/D⁰ ratio compared to the fragmentation baseline is observed in Au+Au collisions, and in p+p/Pb collisions. Measurements of bottom decay daughters at low p_T indicate they are less suppressed when compared with light and charm hadrons. Precision measurements of charm baryon and open bottom production over a broad momentum range are needed for detail understanding of parton energy loss mechanisms and to characterize QGP transport properties.

sPHENIX is a planned next generation high-rate jet, Upsilon and open heavy-flavor detector at RHIC. A state-of-the-art MAPS-based silicon detector (MVTX) is proposed to greatly enhance heavy flavor detection capabilities. In this talk, we will present simulation studies of Λc baryon and open bottom hadron measurements in Au+Au collisions at √s_NN = 200 GeV utilizing full sPHENIX tracking capabilities with MVTX. The simulation method for estimating expected signal and background will be discussed. Statistical projections of open bottom nuclear modification factor and elliptic flow as well as the Λ_c/D⁰ ratio, will be presented.
