Detailed Description

Interface for Collinear Parton Distribution Functions (CPDFs).

This class provides a type-erased interface for accessing CPDFs. The class handles:

• Single flavor CPDF evaluation with pdf(flavor, x, mu2)
• All flavors TMD evaluation with tmd(x, kt2, mu2, cPDFs)

Copy constructor for ICPDF objects.

This constructor creates a new ICPDF object as a copy of another ICPDF object.

Parameters

other

The ICPDF object to copy.

default

operator=() [2/2]

ICPDF& PDFxTMD::ICPDF::operator= ( ICPDF const &  other )

inline

Assignment operator for ICPDF objects.

This operator assigns the value of another ICPDF object to the current ICPDF object.

Parameters

other

The ICPDF object to assign from.

Returns

A reference to the current ICPDF object.

pdf() [1/2]

void PDFxTMD::ICPDF::pdf ( double  x, double  mu2, std::array< double, 13 > &  output  ) const

inline

Evaluate the array of Collinear PDF values for {tbar, bbar, cbar, sbar, ubar, dbar, g, d, u, s, c, b, t}.

This function evaluates the CPDF for all flavors given x and mu2, and stores the results in the output array.

Parameters

x	The momentum fraction of the parton.
mu2	The factorization scale squared.
output	The array to store the CPDF values for all flavors.

pdf() [2/2]

double PDFxTMD::ICPDF::pdf ( PartonFlavor  parton, double  x, double  mu2  ) const

inline

Evaluate the CPDF for a specific flavor.

This function evaluates the CPDF for a given flavor, x, and mu2.

Parameters

flavor	The parton flavor to evaluate the CPDF for.
x	The momentum fraction of the parton.
mu2	The factorization scale squared.

Returns

The value of the CPDF for the given flavor, x, and mu2.
