sPHENIX tracking discussion

[Ming Liu <ming AT bnl.gov>]

HI Hugo,

Very interesting results!

I guess in the AuAu collisions with high multiplicity, the track finding/connecting hits  could be of great challenge as TPOT is far away from INTT? Or this is not an issue?

 

Cheers,

Ming

Subject: [Sphenix-tracking-l] Momentum resolution in TPOT

 

Hi, 

 

following some discussion at the last general meeting and the last software meeting I had a look at the momentum resolution you get when fitting tracks with MVTX, INTT and TPOT only, in TPOT acceptance (which is ~ 5% of the total acceptance in phi) and ignoring the TPC clusters for the time beeing.

The results are in the slides attached first with the current (over optimistic) TPOT spacial resolution, second with more realistic values.

This assumes that the detectors are perfectly aligned, and that track matching between INTT and MVTX to TPOT works (right now relying essentially on the TPC).

 

Note: for some reason my current simulations give a slightly worse momentum resolution that what we have in the have in e.g. the QA, when using MVTX, INTT and TPC, but that does not change the conclusions dramatically.

 

Comments welcome

 

Hugo
