[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
