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).
