Member Function Documentation

virtual TransverseMomentum ThePEG::GaussianPtGenerator::generate ( ) const [virtual]

Generate ( $k_x, k_y$ ) components of the transverse momentum.

They will be distributed as $\exp(-k_\perp^2/\sigma^2)k_\perp dk_\perp$ with $k_\perp^2=k_x^2+k_y^2$ and $\sigma=$ theSigma. The distribution is cutoff at $k_\perp=$ theUpperCut.

Implements ThePEG::PtGenerator.

void ThePEG::GaussianPtGenerator::persistentOutput ( PersistentOStream & os ) const

Function used to write out object persistently.

Parameters:

os

the persistent output stream written to.

Reimplemented from ThePEG::Interfaced.

void ThePEG::GaussianPtGenerator::persistentInput	(	PersistentIStream &	is,
		int	version
	)

Function used to read in object persistently.

Parameters:

	is	the persistent input stream read from.
	version	the version number of the object when written.

Reimplemented from ThePEG::Interfaced.

virtual IBPtr ThePEG::GaussianPtGenerator::clone ( ) const [protected, virtual]

Make a simple clone of this object.

Returns:: a pointer to the new object.

Implements ThePEG::InterfacedBase.

virtual IBPtr ThePEG::GaussianPtGenerator::fullclone ( ) const [protected, virtual]

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.

Member Data Documentation

Energy ThePEG::GaussianPtGenerator::theSigma [private]
