The default constructor.
Definition at line 40 of file PairPtCut.h.

protectedvirtual |
Make a simple clone of this object.
Implements ThePEG::InterfacedBase.
|
virtual |
Describe the currently active cuts in the log file.
Reimplemented from ThePEG::TwoCutBase.
|
inline |
Return the matchers for a pair of particles to cut on.
Only a pair of particles, matching these objects, will be affected.

protectedvirtual |
Make a clone of this object, possibly modifying the cloned object to make it sane.
Reimplemented from ThePEG::InterfacedBase.
|
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.
|
inline |
Return the maximal allowed pair pT.
Definition at line 116 of file PairPtCut.h.
References theMaxPt.
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.
Implements ThePEG::TwoCutBase.
Definition at line 77 of file PairPtCut.h.
References ThePEG::ZERO.
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.
Implements ThePEG::TwoCutBase.
Definition at line 97 of file PairPtCut.h.
References ThePEG::ZERO.
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.
