The KMatrix class is a base class for the implementation of K-matrix parameterizations in Herwig.
|
virtual |
Compute the amplitdes given the \(P\)-vector.
Whether | or not to multiply by \(\prod_i(1-s/m^2_i)\) to regularise the poles |
|
protectedvirtual |
Initialize this object after the setup phase before saving an EventGenerator to disk.
InitException | if object could not be initialized properly. |
Reimplemented from ThePEG::InterfacedBase.
Reimplemented in Herwig::KPiIHalfFOCUSKMatrix, Herwig::KPiIThreeHalfFOCUSKMatrix, and Herwig::PiPiAnisovichKMatrix.
|
inline |
|
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.
|
pure virtual |
Compute the K-matrix for a given scale.
s | The scale |
Whether | or not to multiply by \(\prod_i(1-s/m^2_i)\) to regularise the poles |
Implemented in Herwig::KPiIHalfFOCUSKMatrix, Herwig::KPiIThreeHalfFOCUSKMatrix, and Herwig::PiPiAnisovichKMatrix.
|
inline |
The assignment operator is private and must never be called.
In fact, it should not even be implemented.
void Herwig::KMatrix::persistentInput | ( | PersistentIStream & | is, |
int | version | ||
) |
Function used to read in object persistently.
is | the persistent input stream read from. |
version | the version number of the object when written. |
void Herwig::KMatrix::persistentOutput | ( | PersistentOStream & | os | ) | const |
Function used to write out object persistently.
os | the persistent output stream written to. |
