Detailed Description

Matching metadata for a Wilson coefficient at a specific QCD order.

A MatchingInfo describes:

• sources: the set of parameters required to compute the coefficient at this order,
• compute: a function taking a ParamSrc view and producing the scalar coefficient value,
• lhaid: the LHA identifier under which this coefficient/order/type is stored.

Default behavior:

• compute defaults to a lambda returning 0.0 (safe no-op),
• sources defaults to empty,
• lhaid is default-constructed unless provided.

Notes:

• The compute function signature matches the dependency system’s “source view” pattern: the caller provides a ParamSrc (or similar) that can query source parameters efficiently.

MatchingInfo::MatchingInfo ( )

inline

Default ctor: sets compute to a safe no-op (returns 0.0).

Definition at line 80 of file Wilson.h.

MatchingInfo() [2/5]

MatchingInfo::MatchingInfo ( const LhaID &  id )

inline

Constructs a MatchingInfo with only an LHA id.

Parameters

id	LHA identifier to associate to this order.

Definition at line 87 of file Wilson.h.

MatchingInfo() [3/5]

MatchingInfo::MatchingInfo ( std::unordered_set< ParamId >  src, std::function< scalar_t(const ParamSrc &)>  comp, LhaID  id  )

inline

Full constructor.

Parameters

src	Source parameter IDs.
comp	Compute function.
id	LHA identifier associated with the result.

Definition at line 95 of file Wilson.h.

MatchingInfo::MatchingInfo ( MatchingInfo &&  mi )

default

MatchingInfo() [5/5]

MatchingInfo::MatchingInfo ( const MatchingInfo &  mi )

default

Member Function Documentation

operator=()

MatchingInfo MatchingInfo::operator= ( const MatchingInfo &  mi )

inline

Copy assignment operator.

Copies sources/compute/lhaid from mi.

Member Data Documentation

compute

std::function<scalar_t(const ParamSrc&)> MatchingInfo::compute

Initial value:

=
        [](const auto&) { return 0.0; }

Computation function for this coefficient/order.

Takes a ParamSrc providing access to source values and returns the resulting Wilson coefficient (scalar part). Complex coefficients can be represented upstream by multiple scalar entries (e.g. real/imag).

Definition at line 73 of file Wilson.h.

lhaid

LhaID MatchingInfo::lhaid

LHA identifier used to store the coefficient value in its storage block.

Definition at line 77 of file Wilson.h.

sources

std::unordered_set<ParamId> MatchingInfo::sources = {}

Set of source parameter identifiers used by compute().

Definition at line 64 of file Wilson.h.
