◆ compute_observable() [1/2]

std::vector< ObservableValue > BKstarGammaDecay::compute_observable ( ObservableId obs )

overridevirtual

Compute an observable given an internal observable identifier.

Parameters

obs	Internal observable id.

Returns: One or more results as ObservableValue.

Implements DecayParent.

Definition at line 63 of file BKstarGammaDecay.cpp.

◆ compute_observable() [2/2]

std::vector< ObservableValue > BKstarGammaDecay::compute_observable ( Observables obs )

overridevirtual

Compute an observable given a public observable enum.

Parameters

obs	Observable enum id.

Returns: One or more results as ObservableValue.

Note: Some observables are binned; return multiple values or fill ObservableValue::bin.

◆ get_config()

std::any BKstarGammaDecay::get_config ( ) const

inlineoverridevirtual

Return the current decay configuration when the decay has one.

The base implementation returns an empty std::any. Configurable decays that keep runtime options, such as form-factor source or internal thread count, override this so ObservableInterface worker clones can reproduce the same physics setup as the parent interface.

Reimplemented from DecayParent.

◆ load_params()

void BKstarGammaDecay::load_params ( )

overridevirtual

Load and cache parameters needed by this decay.

Derived classes should read all relevant inputs through the proxies (e.g. p, w_proxy, iobs_qcdp) and store them internally.

This is called by enable after Wilson has been built and the proxy is ready.

config Parsed configuration object.
