Detailed Description

Function Documentation

◆ weightxxQ() [1/2]

double LHAPDF::weightxxQ ( int  id1,
int  id2,
double  x1,
double  x2,
double  Q,
const PDF basepdf,
const PDF newpdf,
double  aschk = 5e-2 
)
inline

Get the PDF reweighting factor for two beams, one with id1,x1 and the other with id2,x2, from basepdf to newpdf

Note
For NLO calculations, in general different PDF values enter for each counterterm: be careful.

◆ weightxxQ() [2/2]

template<typename PDFPTR >
double LHAPDF::weightxxQ ( int  id1,
int  id2,
double  x1,
double  x2,
double  Q,
const PDFPTR  basepdf,
const PDFPTR  newpdf,
double  aschk = 5e-2 
)
inline

Get the PDF reweighting factor for two beams, one with id1,x1 and the other with id2,x2, from basepdf to newpdf

Note
