dE/dx Spectrum - 350 MeV pions/protons

MC - straight tracks - 70% Ar / 30% CO_2 - Magnetic field on

Energy depositions per tracklength for 350 MeV pions/protons


Log likelihoods as a function of #hits

log(L) (1 hit) = log(P_pion/P_proton)


log(L) (2 hits) = log(P_pion/P_proton)_1hit + log(P_pion/P_proton)_2hit

log likelihood for 350 MeV pions/protons - 1 hit.
log likelihood for 350 MeV pions/protons - 2 hits.
log likelihood for 350 MeV pions/protons - 3 hits.
log likelihood for 350 MeV pions/protons - 4 hits.
log likelihood for 350 MeV pions/protons - 5 hits.


Upcoming:

  • Kaons
  • toyMC -> 15 hits
