aboveAlpha()

bool Herwig::IFLightTildeKinematics::aboveAlpha ( ) const

inlinevirtual

Reimplemented from Herwig::TildeKinematics.

Definition at line 68 of file IFLightTildeKinematics.h.

clone()

virtual IBPtr Herwig::IFLightTildeKinematics::clone ( ) const

protectedvirtual

Make a simple clone of this object.

Returns

a pointer to the new object.

Implements ThePEG::InterfacedBase.

doMap()

virtual bool Herwig::IFLightTildeKinematics::doMap ( )

virtual

Perform the mapping to the tilde kinematics for the last selected process and store all dimensionless variables in the subtractionParameters() vector.

Return false, if the calculation of the tilde kinematics was impossible for the selected configuration and true on success.

Implements Herwig::TildeKinematics.

protectedvirtual

Make a clone of this object, possibly modifying the cloned object to make it sane.

Returns

a pointer to the new object.

Reimplemented from ThePEG::InterfacedBase.

Init()

static void Herwig::IFLightTildeKinematics::Init ( )

static

The standard Init function used to initialize the interfaces.

virtual

Return the pt associated to the last merged splitting.

void Herwig::IFLightTildeKinematics::persistentOutput

(

PersistentOStream &

os

)

const

Function used to write out object persistently.

Parameters

os	the persistent output stream written to.

zBounds()

virtual pair< double, double > Herwig::IFLightTildeKinematics::zBounds ( Energy  pt, Energy  hardPt  ) const

virtual

Given a pt, return the boundaries on z.
