TPC dE/dx vs rigidity in 13 TeV pp collisions showing deuterons and anti-deuterons
*Here are comments by the TPC group*
---
- since this plot emphasizes the nuclei production and their assymetry in particle versus anti-particle, it would be interesting to see the total dynamic range (until channel 1200 instead of 600 in this reprsentation)
- could you try a logarithmic scale on the p/z axis? This would further emhasize the nuclei
- there seems to be a binning issue, the granularity along the dE/dx axis is too high; this leads to artificial horizontal lines which are visible in the pdf plot. Could you rebin bya factor 2 or 4 along the dE/dx axis?
- the background between particle lines should be further cleaned up; this has been done for the PDG plot and should be repeated here; this is not required for the SQM approval but should be done at a later time;
- the symbol for the pions is barely visible, the symbol for tritons is missing.
- ALICE performance and pp @ 13 TeV should be put in two lines and be made bigger
