sPHENIX is a new detector at RHIC.

My notes are below and also attached to today’s agenda page at https://indico.bnl.gov/event/20367/

Jaeyyum
=======

Slide 5: axis label should be N_pixels/cluster

Slide 6: axis label on the left should be spelled out as “Cluster Pattern ID”
Need to add a note that 1-pixel pattern is not considered.

Long discussion on how to best present this plot. There was a suggestion to order the patterns by the number of pixels so to that pattern 1&2 would be what is currently pattern 2&3. Then follow with all 3-pixel patterns etc…
It would really help interpret the graph.

Slide 7 use square plots for correlation plots

Slide 8 lots of questions on crude tracking

Slide 10 in real data (not simulation) it is unclear the vertex is expected at (0,0) it all depends on beam steering.

Tim & Ejiro
========
LEGO PLOTS
Slide 3 - eta  phi labels should be better centered
Questions on how event display look with tower by tower threshold
Note on the plot peripheral or MbD charge/max charge<20%

Consensus was to look at higher pt~20 GeV event since we don’t think that jet at 10 GeV at this stage are real 

Virginia
======
Slide 3 - some concern that the slope of the distribution seems unphysical at 40-50 GeV

There was a request to double check if the spectrum is consistent with the 4.5M minimum bias event sample
(Offline both Marzia and Megan agreed that it is not). Marzia’s estimate is in the attached slides.

Best regards

Marzia
