protectedvirtual

Make a simple clone of this object.

Returns: a pointer to the new object.

Returns: a pointer to the new object.

Reimplemented from ThePEG::InterfacedBase.

◆ Init()

static void ThePEG::SimpleDISCut::Init ( )

static

The standard Init function used to initialize the interfaces.

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

		tcPDPtr	pj
	)		const

virtual

Return the minimum allowed value of \(\Delta R_{ij}=\sqrt{\Delta\eta_{ij}^2+\Delta\phi_{ij}^2}\) of two outgoing partons of type pi and pj.

Returns zero.

Implements ThePEG::TwoCutBase.

virtual double ThePEG::SimpleDISCut::minDurham	(	tcPDPtr	pi,
		tcPDPtr	pj
	)		const

virtual

Return the minimum allowed value of the Durham \(k_\perp\)-algorithms distance measure.

This is defined as \(2\min(E_j^2, E_j^2)(1-\cos\theta_{ij})/\hat{s}\) for two outgoing partons. Returns zero.
