Member Function Documentation

virtual IBPtr ThePEG::GaussianPtGenerator::clone ( ) const

protectedvirtual

Make a simple clone of this object.

Returns:: a pointer to the new object.

Implements ThePEG::InterfacedBase.

virtual IBPtr ThePEG::GaussianPtGenerator::fullclone ( ) const

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.

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.
