How to simulate new particle in GSTAR
' ====================================================== '
An example of how to add one particular particle specie is given in
"How to simulate D mesons" page. Here one can find some additional information
on how to choose new particle ID. In fact one should remember for proper
transmission of hep id from event generators, that only the hep Id is meaningfull.
The existing list is below:
In rough order of multiplicity: gamma,pi+,pi-,pi0,etc.
22 GAMMA | 211 PION + | -211 PION - | 111 PION 0 | 130 KAON 0 LONG |
321 KAON + | -321 KAON - | 310 KAON 0 SHORT | 221 ETA | |
2212 PROTON | 2112 NEUTRON | -2212 ANTIPROTON | -2112 ANTINEUTRON | -11 ELECTRON |
11 POSITRON | -12 NU_E | 12 ANTI NU_E | -13 MUON + | 13 MUON - |
3122 LAMBDA | 3222 SIGMA + | 3212 SIGMA 0 | 3112 SIGMA - | 3322 XI 0 |
3312 XI - | 3334 OMEGA - | |||
-3122 ANTILAMBDA | -3222 ANTISIGMA - | -3212 ANTISIGMA 0 | -3112 ANTISIGMA + | -3322 ANTIXI 0 |
-3312 ANTIXI + | -3334 ANTIOMEGA + | |||
-15 TAU+ | 15 TAU- | 441 D+ | -441 D- | 421 D0 |
-421 ANTID0 | 431 DS+ | -431 DS- | ||
24 W+ | -24 W- | 23 Z0 | -14 NU_M | 14 ANTINU_M |
-16 NU_T | 16 ANTINU_T | 71 GEANT | 72 GEANT | 75 GEANT |
700201 DEUTERON | 700301 TRITON | 700202 ALPHA | 700302 HE3 |
It's been agreed some tome ago to use 700000+A*100+Z for atoms, but apart from this there is no conventions.
It is recommended to use something which is consistent with PYTHIA manual. For example it has pdg codes 80-100 reserved for "non-standard" particles or whatever you find logical.
Once a pdg code is selected, one have to put it in local copy of gstar_part.g with a geant code and decay table.
