virtual |
Generate a momentum fraction.
If the PDF contains strange peaks which can be difficult to handle, this function may be overwritten to return an appropriate for a z uniformly distributed in ]0,1[. Also the jacobobian of the
variable transformation must in the function multiply the jacobian argument. The default version will simply use the function
(where the limits are set by cut).
Reimplemented from ThePEG::PDFBase.

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.
Reimplemented from ThePEG::PDFBase.
The assignment operator is private and must never be called.
In fact, it should not even be implemented.

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. |
Reimplemented from ThePEG::PDFBase.
void ThePEG::BudnevPDF::persistentOutput | ( | PersistentOStream & | os | ) | const |
Function used to write out object persistently.
os | the persistent output stream written to. |
Reimplemented from ThePEG::PDFBase.
|
virtual |
The density.
Return the pdf for the given parton inside the given particle for the virtuality partonScale and logarithmic momentum fraction l . The particle is assumed to have a virtuality particleScale.
Reimplemented from ThePEG::PDFBase.
|
virtual |
The valence density.
Return the pdf for the given cvalence parton inside the given particle for the virtuality partonScale and logarithmic momentum fraction l . The particle is assumed to have a virtuality particleScale. If not overidden by a sub class this will return zero.
Reimplemented from ThePEG::PDFBase.
