1 5 78 Each row in the table describes a particle - antiparticle pair. The rows consist of 10 fields: 1. "Full name" - full name of particle. Just for clear orientation, not processed anywhere. 2,3. "A", "A+" - contain designations of the particle and antiparticle, respectively. Any character is allowed. The name may contain one symbol, two symbols or three symbols starting from '~'. For a completely neutral particle the "A" and "a" fields must be identical. 4. "2*Spin" - doubled particle spin: 0 for scalar, 1 for spinor and 2 for vector particles. Spin 1/2 particle (2*Spin = 1) identical with its antiparticle is treated as a Majorana particle. 5. "Mass" - mass identifier or symbol '0'. Its value must be defined in the "Parameters" or "Constraints" table. If this field contains zero, then CompHEP considers the particle as massless. 6. "Width" - particle decay width. Must be '0' or a defined identifier. 7. "Color" - the color SU(3) group representation dimension. You have to choose among 1,3,8. Unity corresponds to colorless particle. Three corresponds to color triplet (fundamental representation). In this case the anti-particle "A+" is transformed by conjugated 3-bar representation. Eight corresponds to color octet (adjoint representation). 8. "Aux" - auxiliary field, which allows to change a particle propagator and add ghost (unphysical) fields. See manual for details. 9,10 "LaTeX(A)" and "LaTeX(A+)" - LaTex names for the corresponding particles.
