Basic Requirements

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

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

  • 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):

  • a similar emission pattern is predicted for the dominant low energy part of the emitted protons
