Leptogluons couple an electron to a gluon and have colour and spin 1/2 or spin 3/2. We consider only the spin 1/2 leptogluon in this generator. The width of the leptogluon is given by
where is the leptogluon mass,
the
strong coupling constant evaluated at the QCD scale
and
the scale of the interaction
strength
(the inverse
scale of possible substructure).
The differential cross-section is given by
where ,
and g is the gluon
density in the proton at momentum fraction x and QCD scale
.
Using the narrow width approximation, the cross-section reduces to
The possible reaction proceeding from an electron beam is
An equivalent process has also been coded for a positron beam.
