Detailed Description

Provides electromagnetic coupling values at requested energy scales.

QEDProvider is a thin convenience wrapper around EWHelper, offering a callable interface for computing the electromagnetic coupling $\alpha_{\text{em}}(\mu)$ from an AlphasConfig.

Note: EWHelper::alpha_em does not implement generic running and throws std::logic_error instead of returning a placeholder value. Code requiring the precomputed special values should read them from the EW block populated by EWHelper::Init().

Typical usage:

QEDProvider qed;
AlphasConfig a_cfg{ .scale = 91.1876 };
 
double alpha_em = qed(a_cfg);

◆ operator()()

double QEDProvider::operator() ( AlphasConfig config )

Computes the electromagnetic coupling $\alpha_{\text{em}}$ at a given scale.

Delegates to EWHelper::alpha_em using the renormalization scale stored in the supplied configuration.

Parameters

config AlphasConfig object containing the target scale.

Returns: Value of $\alpha_{\text{em}}$ at the specified scale, as returned by EWHelper.
