Dear Experts,
I wanted to plot the theoretically calculated Bethe-Bloch curve (dE/dx vs p) for the ALICE TPC for different particles (e-, pions, muons, kaons etc). I could not find any documentations for it. Could you kindly help in finding the macros or data set for this. (by bethe bloch curve i meant the curve used to calculate the tpcNSigma for different particles ).
Dear Anantha,
in slide 3 of Sign in to CERN
you find the equation of the Bethe Bloch parametrization. The 5 parameters are the 5 parameters stored in the OCDB for each period.
Best regards,
Ana
