Detailed Description

Provides strong coupling constant and MS-bar mass values at various energy scales.

QCDProvider is a thin convenience wrapper around QCDHelper, offering a callable interface for:

computing the strong coupling $\alpha_s(\mu)$ from an AlphasConfig,
computing running MS-bar quark masses at scale $\mu$ from a MassConfig,
accessing the underlying QCDConstants used in these calculations.

Typical usage:

QCDProvider qcd;
AlphasConfig a_cfg{ .scale = 91.1876, .m_b_type = MassType::POLE, .m_t_type = MassType::POLE };
MassConfig   m_cfg{ .pdg_id = 5, .scale = 4.2, .m_b_type = MassType::POLE, .m_t_type = MassType::POLE };
 
double alpha_s_mZ = qcd(a_cfg);
double mb_MSbar   = qcd(m_cfg);
auto*  consts     = qcd.get_constants();

Examples: data_provider_example.cpp.

◆ get_constants()

QCDConstants * QCDProvider::get_constants ( )

overridevirtual

Retrieves the constants related to QCD calculations.

Provides access to the QCDConstants structure used internally by QCDHelper (Casimir operators, beta-function coefficients, etc.).

Returns: Pointer to QCDConstants structure.

Implements IQCDProvider.

◆ operator()() [1/2]

double QCDProvider::operator() ( AlphasConfig config )

Computes the strong coupling constant $\alpha_s$ at a given scale.

Delegates to QCDHelper::alpha_s, using the configuration provided (renormalization scale and mass-scheme choices for b and t quarks).

Parameters

config AlphasConfig object containing scale and mass type settings.

Returns: Value of $\alpha_s$ at the specified scale.

Definition at line 3 of file QCDProvider.cpp.

◆ operator()() [2/2]

double QCDProvider::operator() ( MassConfig config )

Computes the MS-bar running mass at a given scale for a quark.

Delegates to QCDHelper::msbar_mass using the supplied MassConfig (PDG ID, renormalization scale, and mass schemes).

Parameters

config MassConfig object containing PDG ID and scale information.

Returns: The MS-bar mass at the specified scale.
