Hi Yuri, Everyone,

I was wondering if you have had a chance to look at my slides containing the DCA distributions, or the files I put on RCF, and if you have any further ideas to look into. I am very much looking forward to hearing about any insights you may have. I will have additional QA and physics plots to show on Thursday which I hope will also move the discussion forward.

Hello again everyone,

I have uploaded distributions of DCA and nHITS over the entire (eta, pT) phase space on RCF under the following directory:  /star/u/mlabonte/QA_PNG  (aptly named because it contains many, many PNG files)

There are subdirectories, pertaining to nHITS and DCA. 

With Respect to DCA: there are both comparisons of the test production to P24ia, and the test production to embedding samples. These each have their own directory.

Inside the P24ia-test-production-comparison folder, it is further divided into three directories: one for analysis done only on sectors in which there was a significant amount of track breaking (I called these bad sectors), one analysis for sectors in which there was negligible track breaking (good sectors), and one for all TPC sectors. To ensure I am selecting tracks who end up in the correct sector, the good/bad sector analysis has a minimum pT cut of 0.4 GeV. 

The nHits folder only has one folder inside of it containing comparisons of test production to embedding. I haven’t made plots of comparisons of test production to P24ia, since the main feature in the old production was the double peaked structure due to track breaking is now gone in the new production. I am still happy to make those comparisons too if needed. However, it does look like there are some residual features in the nHits distributions in far forwards eta, as well as close to the target when we compare to embedding. See the slides I sent earlier for more details. 

I have sliced up the phase space in very fine bins of eta and pT. This has resulted in a great deal of one-dimensional distributions produced for these studies, and part of the reason why I consolidate all this information in the two-dimensional plots of the means of these distributions. I recommend downloading the entire folders, and viewing on your own machine in “”gallery mode”, and view the folder as a sort of “flip book” as you scroll through the phase space (i.e, hold down the arrow key, and let the images flip by quickly, almost like a movie, until you come across a feature you would like to view in more detail). The PNG files are named for their positions in rapidity and pT space, and should be intuitive. 

I apologize for the large volume of files, but I hope it is useful.

Hi everyone,

Please find attached my slides presented today. It also includes some of the distributions Yuri was asking about. I will send a link shortly that includes distributions over the full phase space (eta, pT) for DCA XY and nHits.
