Square of qg->gqge+e- Z+Jets Unordered Current.

Parameters

pa	Momentum of initial state quark
pb	Momentum of initial state gluon
pg	Momentum of final state unordered gluon
p1	Momentum of final state quark
p2	Momentum of final state gluon
pep	Momentum of final state positron
pem	Momentum of final state electron
aptype	Initial particle 1 type
bptype	Initial particle 2 type
zprop	Mass and width of the Z boson
stw2	Value of sin(theta_w)^2
ctw	Value of cos(theta_w)

Returns: Square of the current contractions for qg->gqge+e- Scattering

This returns the square of the current contractions in qg->gqg scattering with an emission of a Z Boson.
