## IntroductionColorFull is a C++ package for color summed calculations in QCD. ## Technical overviewHere a brief overview of the ColorFull classes is given, for details To treat the color structure ColorFull uses the classes: - Quark_line: a Polynomial times a closed (1,2,3,4)=Tr(t^g1 t^g2 t^g3 t^g4)
or an open {1,3,4,2}=(t^g3 t^g4)^q1_q2 quark-line. - Col_str: a Polynomial*(product of Quark_lines).
- Col_amp: a sum of Col_strs + Scalar. Scalar is a Polynomial and is used for
containing the Polynomial resulting after having contracted all color indices. - Col_basis, Trace_basis, Tree_level_gluon_basis and Orthogonal_basis:
These are basis classes for containing QCD color bases. A basis vector is a Col_amp.
Apart from this, ColorFull also has simple classes for basic treatment of the - Monomial: Nc^pow_Nc*CF^pow_CF*TR^pow_TR*int_part*cnum_part
- Polynomial: a sum of Monomials
- Poly_vec: a vector of Polynomials
- Poly_matr: a matrix of Polynomials
Finally there is a library class for evaluations: - Col_functions: This is a library class with functions for:
- numerical evaluation
- leading Nc evaluation
- scalar products
- gluon exchange
- gluon emission
- color correlator < c | T_i T_j | c >
- soft anomalous dimension color matrices
