[Category:Model](/Category:Model "wikilink") In contrast to [supersymmetric models](/Nomenclature_for_fields_in_supersymmetric_models "wikilink"), there is no strict convention for the first letter in the names of fermions and scalars. However, for gauge fields the following conventions exists:
|
|
|
|
|
|
1. Vector bosons must have `V` as first letter
|
|
|
2. Ghosts names are derived from vector boson and start always with `g`
|
|
|
|
|
|
Otherwise, the conventions are the same as for supersymmetric models:
|
|
|
|
|
|
1. Particles carry in general a list with indices, which can be
|
|
|
1. `generation`: For all particles which appear in more than one generation
|
|
|
2. `lorentz:` For all particles carrying a Lorentz index
|
|
|
3. `charge:` For all fields which are charged under a unbroken, non Abelian gauge group
|
|
|
2. Antiparticles are assigned via
|
|
|
1. `conj`: scalars, Weyl spinors, vector bosons
|
|
|
2. `bar`: Dirac spinors, ghosts
|
|
|
|
|

Examples
|
|
|
--------
|
|
|
|
|
|
1. Names and indices
|
|
|
1. `VP[{lorentz}]`: Photon
|
|
|
2. `gP[{lorentz}]`: Photon ghost
|
|
|
3. `VG[{color,lorentz}]`: Gluon with one index for the adjoint of the color group and one Lorentz index
|
|
|
4. `hh[{generation}]`: Neutral, CP-even Higgs (light and heavy Higgs) after EWSB
|
|
|
2. Anitparticles
|
|
|
1. `conj[VWm]`: anti-partilce of *W*<sup>−</sup>
|
|
|
2. `bar[Fe]`: anti-leptons
