sPHENIX MAPS tracker discussion

["Liu, Ming Xiong" <mliu AT lanl.gov>]

Dear all,

 

Thanks for the comments on the MVTX/HF abstract. The abstract is updated and submitted.

Open Heavy Flavor Physics Program with the sPHENIX MVTX Detector at RHIC

 

The sPHENIX is the next generation heavy ion physics experiment designed to collect a suite of unique hard probes with unprecedented statistics and kinematic reach at RHIC. The sPHENIX Monolithic Active Pixel Sensor (MAPS) based VerTX detector (MVTX) will utilize the next generation fast MAPS technology developed at CERN to provide precision tracking with high efficiency over a broad momentum range at high luminosity in p+p, p+Au and Au+Au collisions envisioned at RHIC. MVTX enables precision measurements of open heavy flavor observables, covering an unexplored kinematic regime at RHIC energies, in particular the nuclear modification and flow of $b$-jets and $B$-mesons, which collectively cover a wide transverse momentum range of 2--35~GeV$/c$. Together with the light-quark observables, these $b$-quark probes will provide essential information to the microscopic description of QGP at RHIC energies. The physics program and detector development of MVTX will be discussed.

 

Cheers,

Ming
