sPHENIX discussion of physics

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

Hi Dennis,
    Thanks a lot for your very nice suggestions and feedback. I have 
updated my current talk draft accordingly and I look forward to include 
more sPHENIX performance plots from the tracking subsystems once they 
are approved.

    Please see the updated talk slides below:

    And please see my response inline below.

    Further suggestions and comments are very welcome!
    Thanks.
                                                   Xuan

performance plots once they are approved.

---> Updated the relevant sentence as suggested.

---> Updated the statement as suggested.

---> Updated the statement as suggested.
