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.
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.
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.
Implements ThePEG::TwoCutBase.
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.
Implements ThePEG::TwoCutBase.
Return the minimum allowed squared invariant mass of two outgoing partons of type pi and pj.
Returns zero.
Implements ThePEG::TwoCutBase.
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.
Returns zero.
