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

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.

|
- 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):

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