sPHENIX tracking discussion

[Sourav Tarafdar <sourav.pheonix AT gmail.com>]

Dear all,

The revised version of the QM17 poster based in Dave's suggestion is located here

https://indico.bnl.gov/getFile.py/access?contribId=4&resId=0&materialId=slides&confId=2794

Sorry , I overlooked the magnetic field in the abstract part. It is corrected to 1.4 T from 1.5 T.

Regarding Gunther's comment about tracking efficiency , the ones on my poster are for pure pions only while the one in Veronica's poster are Hijing embedded pions. Also Veronica is presenting the new way of defining track efficiency which is different than what we have been seeing so far. Thanks Gunther for bringing this up. Now I have added a line saying the tracking performance plots are related to pure pions. I hope this clarifies things to the audience. 

Thanks

-Sourav

Hi Sourav,

To be consistent with the advice Tony gave Veronica about her poster,
you should probably change the 1.5 Tesla to 1.4 Tesla.

Cheers,
Dave
