Detailed Description

In a trace basis the basis vectors are closed or open quark-lines or products of close and open quark-lines.

Constructor & Destructor Documentation

◆ Trace_basis() [1/3]

ColorFull::Trace_basis::Trace_basis ( )

inline

Default constructor.

◆ Trace_basis() [2/3]

ColorFull::Trace_basis::Trace_basis	(	int	n_quark,
		int	n_gluon
	)

inline

Constructor for creating a trace basis for n_quark qqbar-pairs and n_gluon gluons.

◆ Trace_basis() [3/3]

ColorFull::Trace_basis::Trace_basis	(	int	n_quark,
		int	n_gluon,
		int	n_loop
	)

inline

Constructor for creating a trace basis for n_quark qqbar-pairs and n_gluon gluons, keeping only those color structures that can appear to order n_loop in pure QCD. (Note: For electroweak interactions more color structures may be needed.)

Member Function Documentation

◆ create_basis() [1/2]

void ColorFull::Trace_basis::create_basis	(	int	n_q,
		int	n_g
	)

Creates a trace basis with basis vectors saved in the cb member. Keeps all possible basis vectors, i.e., the basis is valid to any order in perturbation theory.

◆ create_basis() [2/2]

void ColorFull::Trace_basis::create_basis	(	int	n_q,
		int	n_g,
		int	n_loop
	)

Creates a trace basis with basis vectors saved in the cb member. Keeps only basis vectors needed up to n_loop in pure QCD.
