171st Optimization Meeting

Wednesday 19 Jun 2019, 08:00 → 09:00 America/Los_Angeles

Dan Protopopescu

Join via https://stanford.zoom.us/j/867873981, or see email announcement for more details on how to join this meeting remotely.

Present: Amanda, Chris, Dan, Marty, 5 others from Oregon, Rick (Richard Kriske, UMN)

Andy is on holiday this week. 

Minutes: 

• Chris presented his findings related to poor PandoraPFA performance with SiD_o2_v03 when using either Truth Tracks or Conformal Tracks. The problem seems to be a failure to match tracks to clusters: PandoraPFA does not require all tracks to be matched, either due to a too restrictive track selection or a failure of the track/cluster matching criteria. Also, a phi variation showing six dips is bizarre.
• Will check recent CLIC progress wrt tracking (see https://indico.cern.ch/event/764830/contributions/3174667/attachments/1735155/2806170/softwareMeetings_16Oct.pdf; link provided by Amanda) and consult CLIC mentioning Chris' talk.
• Dan works on PID tools for CLIC, scope is being expanded to more general PID efficiency, in contact with Emilia and Andre to understand the full scope of the code development required
• Proposal to create a SiD-specific GitHub repository (e.g. SiD Tools) where SiD would share (analysis) code 

Next meeting: July 17th, unless someone requests a meeting on July 3rd (when Dan is on holiday)

08:05 → 08:25 Preliminary Study of PandoraPFA Failures Using Truth and Conformal Tracks with SiD

PandoraPFA performs poorly with SiD using either Truth Tracks or Conformal Tracks. The problem has been traced to a failure to match tracks to clusters: PandoraPFA does not require all tracks to be matched. The failure is either due to a track selection which is too restrictive or due to a failure of the track/cluster matching criteria.

Speaker: Christopher Thomas Potter (University of Oregon (US))
