sPHENIX discussion of physics

[xuanlipx <xuanlipx AT rcf.rhic.bnl.gov>]

Dear All,
     I apologize that I wrongly sent the link to the old draft (v1) and 
please see the correct link to the updated IS23 sPHENIX HF talk draft 
(v2) below:

     Further suggestions and comments are very welcome!
     Thanks.
                                              Xuan
