Difference: PiddetectorRequirements (r2 vs. r1)

Basic Requirements

  • Momentum vs. polar angle distribution of muons from formation reaction of the psi(3686):

The envisaged physical program (see TPR) of PANDA requires a

  • hermetic detector with nearly 4pi solid angle coverage
  • concurrent detection of lepton pairs
  • good kaon identification from very low energies up to a few GeV/c
  • detection of low energy photons
  • muon detection capability
  • higly segmented low energy threshold electromagnetic calorimeter
  • (second) vertex recognition
  • radiation hardness
  • good PID above particle momenta of 0.5 GeV/c at all angles

Charmed Hybrids

  • Momentum vs. polar angle distribution of decay kaons from the reaction pbar p -> Phi Phi -> 4K at sqrt s = 3.6GeV(Ref. TPR):

  • The distribution demonstrates the need for pion-kaon separation up to ~ 3 GeV/c at forward angles.
