sPHENIX MAPS tracker discussion

[Ming Liu <ming AT bnl.gov>]

Hi Christof, Tony and all,

 

What is the status of evaluating the impact of INTT on vertex seeding in high rate p+p/p+A collisions? It seems this is pretty much the last major item to be resolved to address the recent MVTX review committee’s recommendations:

 

You have already made excellent progress with tracking simulations and showed that:

1. For the global tracking, MVTX+TPC is already showing excellent rejection of pileups in pp collisions, INTT seems not contributing much for further rejection power.   
2. Tracking efficiency seems very similar for 2/3/4 layers of INTT.
3. Di-electron mass resolution prefers less INTT layers (or less mass in general)

 

To me, it seems 2-layer (or 3-layer for high efficiency) INTT already sufficient and preferred for better Upsilon resolutions.

 

Cheers,

Ming
