Hi Yuri,

I am sorry for this misleading cut. As I mentioned before, I only use this tofmass cut to select pion when I want to make the nSigmaPion vs P plot on slide 3. For dE/dx plot on slide 4 and 5, I do not use any TOF information and TOF cut.

Thank you for your attention.

Sincerely,

Chenliang Jin

Hi Chenliang,

  What does mean your cut on slide 2

|tofmass2 - 0.019|< 0.003

?

Hi Yuri and All,

 

I am really sorry that my former slides might be misleading. We only use TOF information to select Pion when we want to make the nSigmaPion vs. P plot. For these dE/dx plot we made, we only use TPC information and do not use TOF information to select pion.

Here is the new link for the report:

Thank you very much for your attention.
