Basic Requirements

  

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

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

Examples

  

Charmonium Spectroscopy

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

  • example for typical momenta
  

  

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.

  

Charmed Hadrons in Nuclear Matter

  • Momentum vs. polar angle distribution of decay kaons from the reaction pbar p -> Phi Phi at sqrt s = 3.6GeV:
  
  • Transverse vs. longitudinal momentum distribution of neutrons obtained with an UrQMD calculation for 4.05GeV/c pbar * Cu, including low energy evaporation processes(Ref. TPR):
