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 \(l=\log(1/x)\) for a z uniformly distributed in ]0,1[. Also the jacobobian of the \(l\rightarrow z\) variable transformation must in the function multiply the jacobian argument. The default version will simply use the function \(l(z) = l_{\min} + z*(l_{\max}-l_{\min})\) (where the limits are set by cut).
Reimplemented from ThePEG::PDFBase.

virtual |
Generate scale (as a fraction of the maximum scale).
If the PDF contains strange peaks which can be difficult to handle, this function may be overwritten to return an appropriate scale \(Q^2/Q^2_{\max}\) for a z uniformly distributed in ]0,1[. Also the jacobobian of the \(Q^2/Q^2_{\max}\rightarrow z\) variable transformation must multiply the jacobian argument. The default version will simply use the function \(Q^2/Q^2_{\max} = (Q^2_{\max}/Q^2_{\min})^(z-1)\) or, if \(Q^2_{\min}\) is zero, \(Q^2/Q^2_{\max} = z\) (where the limits are set by cut).

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

Integrated pomeron/regeon flux over qq in the range qqmin ... qqmax (with normalization constant Ap = 1 GeV2).
The flux normalization constant is obtained \(x_p*intFx_p = 1\), where x_p = 0.003.
