Name: ExcludedVertices
Type: Varying size vector of references to objects of class ThePEG::VertexBase

Description:

Vertices which are not included in the 2 -> 2 scatterings

---

Name: ExcludedExternal
Type: Varying size vector of references to objects of class ThePEG::ParticleData

Description:

Particles which are not allowed as outgoing particles

---

Name: Excluded
Type: Varying size vector of references to objects of class ThePEG::ParticleData

Description:

Particles which are not allowed as intermediates

Name: ScaleFactor
Type: Parameter

Description:

The prefactor used in the scale calculation. The scale used is that defined by scaleChoice multiplied by this prefactor
Default value: 1
Minimum value: 0
Maximum value: 10

Name: ScaleChoice
Type: Switch

Description:

&TwoToTwoProcessConstructor::scaleChoice_
Registered options:

0(Default)

Use if sHat if intermediates all colour neutral, otherwise the transverse mass

1(sHat)

Always use sHat

2(TransverseMass)

Always use the transverse mass

3(MaxMT)

Use the maximum of m^2+p_T^2 for the two particles

Default value: 0

Name: Processes
Type: Switch

Description:

Whether to generate inclusive or exclusive processes
Registered options:

0(SingleParticleInclusive)

Require at least one particle from the list of outgoing particles in the hard process

1(TwoParticleInclusive)

Require that both the particles in the hard processes are in the list of outgoing particles

2(Exclusive)

Require that both the particles in the hard processes are in the list of outgoing particles in every hard process

4(VeryExclusive)

Require that both the incoming and outgoing particles in the hard processes are in the list of outgoing particles in every hard process

Default value: 0

---

Name: IncludeEW
Type: Switch

Description:

Switch to decide which diagrams to include in ME calc.
Registered options:

0(No)

Only include QCD diagrams

1(Yes)

Include EW+QCD.

Default value: 1
