sPHENIX tracking discussion

[Anthony Frawley <afrawley AT fsu.edu>]

Dear Joe,

Quick impressions:

For slide 16, we can come up with a better fit. A double crystal ball fit would be best.  Also, more statistics would be good. I can make one with the default tracking chain, if you like.

I agree with Jin about the plot on slide 15, move the Y axis labels to the center of the bin.

Hi Joe

 

Thanks for the nice slides and congratulations again on the plenary talk!

 

Few suggestions which I hope you find useful:

 

• Slide 5: suggest quantify “huge data rate”, which means different thing for different community. Here we could quote Martin’s buffered continuous data rate to SDCC at the last computing review, which is the relevant rate for this talk.
• Slide 6: could use an display to illustrate the occupancy, such as the one attached.
• Slide 8: “Fun4All-sPHENIX code available on Github”: I think here we can highlight our codebase is open sourced and containerized.
• Slide 15: the right hand plot could use some improvement:

• Shift the bin boundary to 0.5s, i.e. remove the ambiguity between neighboring integers.
• The y-axis title is small, so we could highlight on the plot what the yellow band on y=1 means, so reader do not have to draw their own conclusion.

Slide 16: the Upsilon fit quality is pretty poor, noticeably missing both peak and tail

 

Cheers

 

Jin

Hi Joe,

From a quick look your slides look really nice !

What struck me though: on slide 16, the upsilon inv mass fit is rather poor (in particular there seem to be a flat background component, that does not fit the data at all).

I would try to get a better fit ?

Hi all,

 

Attached is a draft of my slides for CHEP. My talk is next Monday at 11:10 AM EST, and I have a total time slot of 30 minutes so I’ll aim for 25+5. Any comments/suggestions are welcome.
