Detailed Description

User-definable WilsonCoefficient with explicit per-order matching definitions.

This header defines CustomWilson, a convenience concrete implementation of WilsonCoefficient intended for:

• quick prototyping,
• external/custom EFT extensions,
• unit tests, where the user provides the dependency sources and compute functor directly.

Unlike built-in or MARTY-backed coefficients, CustomWilson does not assume any physics computation by itself. Instead, clients fill MatchingInfo per QCD order using set_order_info().

Typical usage

auto c = std::make_shared<CustomWilson>(LhaID(1,2,0,0), "WCUSTOM");
c->set_order_info(QCDOrder::LO,
                  { ParamId{ParameterType::SM,"SMINPUTS",1} },
                  [](const ParamSrc& src){ return src.get_val("SMINPUTS",1); },
                  LhaID(1,2,0,0));
