Operator Classes

The classes are nested as follows:

nesting of the operator classes: solid lines means “has many”, dashed lines means “evolves into”

• OperatorGrid

  • is the master class which administrates all operator tasks

  • is instantiated once for each run

  • holds all necessary configurations

  • holds all necessary instances of the Utility Classes

• Operator

  • represents a configuration for a fixed final scale \(Q_1^2\)

  • performs the actual computation

  • uses the 3-dimensional Operator Anomalous Dimension Basis

  • its OpMember are only valid in the current threshold area

• PhysicalOperator

  • is the connection of the Operator between the different flavor bases

  • is initialized with the 3-dimensional Operator Anomalous Dimension Basis

  • does recombine the operator in the Operator Intrinsic QCD Evolution Basis (see Matching Conditions)

  • exports the operators to Operator Flavor Basis in a ndarray

• OpMember

  • represents a single operator in Mellin space for a given element of the Operator Bases

  • inside Operator they are in Operator Anomalous Dimension Basis

  • inside PhysicalOperator they are in Operator Intrinsic QCD Evolution Basis
