sPHENIX is a new detector at RHIC.

[Chris Pinkenburg <pinkenburg AT bnl.gov>]

we had a brief meeting, talks from Carlos and Tony

Recent repository updates to analyze the test beam data. It was decided to separate this from the previous prototype rather than trying to merge this. Makes our life a little easier.

Carlos: Moving to the new TPC geometry, implemented more realistic readout (binning in eta/rphi) to reflect the real TPC. Takao reduced the number of readout cards in R1 from 6 (as is in the macro)to 5, that will be an option in this macro to choose the number of cards.
pt Resolution suffers a bit and the strange bump at pt<4GeV/c is enhanced (no explanation yet what this is).

Tony: Track refitting tests
Tony played with the genfit refitting. It improves resolution but there are some oddities. The refitted tracks show a double peak structure in the dca distribution as well as a drop at forward eta (my phone cut right here and I had to redial in so I missed this part). Refitting improves the upsilon mass resolution but currently it's at 101MeV which is really not good enough for our upsilon program.

Thanks to everyone who attended
