1. interacting such as hadron, electron, photon or muon

( ( (p->status()%1000 == 1) ||
    (p->status()%1000 == 2 && p->status() > 1000) ) &&
  (p->barcode()<100000) ) 

&&

!( abs(p->pdg_id())==12 || 
   abs(p->pdg_id())==14 || 
   abs(p->pdg_id())==16 ||
   (abs(p->pdg_id())==1000039 &&  p->status()%1000==1 ) ||
   (abs(p->pdg_id())==1000022 &&  p->status()%1000==1 ) )

2. non interacting such as neutrino

abs(p->pdg_id())==12 || 
abs(p->pdg_id())==14 ||
abs(p->pdg_id())==16 ||
(abs(p->pdg_id())==1000039 &&  p->status()%1000==1 ) ||
(abs(p->pdg_id())==1000022 &&  p->status()%1000==1 )

3. stable in a generated event or an input to Geant in a fully simulated event,
   that is, the particle belongs to the final state.

( (p->status()%1000 == 1) || 
  (p->status()%1000 == 2 && p->status() > 1000) )

&&

(p->barcode()<100000)

4. produced by the event generator

p->barcode() < 100000 

&& 

( p->status()<200 ||
  p->status()%1000 == 1 || 
  p->status()%1000 == 2  )
