Detailed Description

Cuts is a class for implementing kinematical cuts in ThePEG.

The class itself only implements cuts on the total momentum of the hard sub-process, implemented as minimum and maximum values of $x_1$ and $x_2$ (or $\hat{s}=x_1x_2S_{tot}$ and $\hat{y}=\log(x_1/x_2)/2$ . Further cuts can be implemented either by inheriting from this base class, in which the virtual cut() function should be overridden, or by assigning objects of class OneCutBase, TwoCutBase and MultiCutBase defining cuts on single particles, pairs of particles and groups of particles in the hard sub-process respectively.

The Cuts object must be initialized specifying the overall laboratory frame, giving the total squared invariant mass, $S$ , and the rapidity, $Y$ , of the colliding particles in this frame. The colliding particles are thus assumed to be directed along the $z$ -axis.

For each event, the Cuts object must also be initialized giving the squared invarint mass, $\hat{s}$ , and the total rapidity, $\hat{y}$ , of the hard sub-process in the center-of-mass frame of the colliding particles. Note that this means that the transformation between the lab frame and the rest frame of the hard sub-process is assumed to be a simple boost along the z-axis.

Member Function Documentation

virtual void ThePEG::Cuts::initialize	(	Energy2	smax,
		double	Y
	)			`[virtual]`

Initialize this object specifying the maximum total invariant mass squared, smax, and the total rapidity, Y, of the colliding particles (for the maximum invariant mass).

A sub-class overriding this function must make sure the base-class function is called. This function should be called once in the beginning of a run.

virtual void ThePEG::Cuts::initEvent ( ) [virtual]

Initialize this object for a new event.

A sub-class overriding this function must make sure the base-class function is called. This function is called before the generation of a new sub-process, before the incoming partons have been generated.

virtual bool ThePEG::Cuts::initSubProcess	(	Energy2	shat,
		double	yhat,
		bool	mirror = `false`
	)			const `[virtual]`

Set information about the invariant mass squared, shat, and rapidity, yhat, of the hard sub-process.

The rapidity should be given wrt. the center of mass of the colliding particles. A sub-class overriding this function must make sure the base-class function is called. This function is called before the generation of a new sub-process, after the incoming partons have been generated. If mirror is true any questions regarding cuts on the sub-process in the functions minYStar(tcPDPtr), maxYStar(tcPDPtr p), passCuts(const tcPDVector &, const vector<LorentzMomentum> &, tcPDPtr, tcPDPtr) and passCuts(const tcPVector &, tcPDPtr t1, tcPDPtr) will assume that the z-axis is reversed in the sub-process rest frame. Returns false if the given values were outside of the cuts.

bool ThePEG::Cuts::passCuts	(	const tcPDVector &	ptype,
		const vector< LorentzMomentum > &	p,
		tcPDPtr	t1 = `tcPDPtr()`,
		tcPDPtr	t2 = `tcPDPtr()`
	)			const

Check if the outgoing particles, with the given types and momenta, from a sub-process passes the cuts.

The particles must be given in the rest frame of tha hard sub-process, and the initSubProcess must have been called before. Also the types of the incoming partons, t1 and t2, may be given if availible.

bool ThePEG::Cuts::passCuts	(	const tcPVector &	p,
		tcPDPtr	t1 = `tcPDPtr()`,
		tcPDPtr	t2 = `tcPDPtr()`
	)			const

Check if the outgoing particles from a sub-process passes the cuts.

The particles must be given in the rest frame of tha hard sub-process, and the initSubProcess must have been called before. Also the types of the incoming partons, t1 and t2, may be given if availible.

bool ThePEG::Cuts::passCuts ( const SubProcess & sub ) const

Check if the incoming and outgoing particles in the given sub-process passes the cuts.

Energy2 ThePEG::Cuts::minSij	(	tcPDPtr	pi,
		tcPDPtr	pj
	)			const

Return the minimum allowed squared invariant mass of two outgoing partons of type pi and pj.

This function first determines the minimum from the corresponding function from in TwoCutBase objects. If no minimum was found, one is derived from minKTClus(), minDurham(), minKT() and minDeltaR(), if possible.

Energy2 ThePEG::Cuts::minTij	(	tcPDPtr	pi,
		tcPDPtr	po
	)			const

Return the minimum allowed value of the negative of the squared invariant mass of an incoming parton of type pi and an outgoing parton of type po.

This function first determines the minimum from the corresponding function from in TwoCutBase objects. If no minimum was found, one is derived from minKT(), if possible.

		tcPDPtr	pj
	)			const

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.

Simply returns the maximum of the results from calling the corresponding function in the TwoCutBase objects.

		tcPDPtr	pj
	)			const

Return the minimum allowed value of the longitudinally invariant $k_\perp$ -algorithms distance measure.

This is defined as $\min(p_{\perp i}, p_{\perp j})\sqrt{\Delta\eta_{ij}^2+\Delta\phi_{ij}^2}$ for two outgoing partons, or simply $p_{\perp i}$ or $p_{\perp j}$ for a single outgoing parton. Returns 0 if both partons are incoming. A null pointer indicates an incoming parton, hence the type of the incoming parton is irrelevant. Simply returns the maximum of the results from calling the corresponding function in the TwoCutBase objects.

		tcPDPtr	pj
	)			const

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