sPHENIX discussion of physics

[Haiwang Yu <yuhw.pku AT gmail.com>]

Dear all,

I'd like to submit the following abstract of a poster for QM2017.

This is a poster focus on the algorithm studies which should complement LANL's B-Jet and MAPS poster.

And this abstract was prepared together with Ming and Jin.

Comments and suggestions are very welcome.

Cheers,

Haiwang

Title: B-Jet Tagging Algorithms for sPHENIX at RHIC

Haiwang Yu, Sanghoon Lim, Jin Huang, Dennis V. Perepelitsa, Michael P. McCumber

Jet initiating from a B-quark (B-jet) is sensitive to the collision energy loss of the quark when traversing through Quark Gluon Plasma (QGP). Among the light jet background, the rare B-jets can be identified by utilizing some characteristic B-hadron decay properties, such as long lifetime and semi-leptonic decay modes. With the proposed sPHENIX detector at RHIC, we study a variety of B-Jet tagging algorithms, including the track impact parameter method, secondary vertex method and the lepton tagging method. The algorithm optimization and their performance projection will be discussed based on comprehensive detector and physics simulations.
