sPHENIX tracking discussion

["Osborn, Joe" <osbornjd AT ornl.gov>]

Hi all,

 

I’ve gone through the reviewer comments for the CHEP paper on tracking and addressed most of them. I’d like to send around an initial draft ASAP so that people have some time to make comments on how best to expand the paper, if at all, given the time constraints. In that regard, there were a few comments left by one reviewer which may help us guide that discussion, which I’d like to copy here to initiate discussion.

 

1. R: Might be useful to quantify the ratio of the number of Si tracklets which match to the TPC tracks... perhaps as a function of pT?
2. The following comment is in response to a paragraph on the timing of the ACTS Kalman Filter track fitting tool, which is what we report (i.e., only the time to run the KF tool per track).

R: Also.  The discussion seems lacking here.  It is essentially "we implemented track fitting using ACTS, and here is the timing".   I would quote the improvement made over the previous sPHENIX track fitting, and make the case that progress has been made towards the 5s/event goal.  And make some comment about needing to make further progress w/respect to track finding.

3. R: If this is allocated a long talk slot, I would hope to see a discussion of track finding, and the strategies to get the timing within budget there.

 

Alternatively, perhaps it would be useful to send a draft around now, let people take a quick look at it to get a general idea of the current scope, and have a dedicated meeting to discuss the expansion of the paper this week?

 

Let me know any immediate thoughts,

 

Joe Osborn
