CHATURVEDI, S.; GUPTA, V.; SANCHEZ-COLON, G.  e  MUKUNDA, N.. Recursive parametrization of quark flavour mixing matrices. Rev. mex. fis. [online]. 2011, vol.57, n.2, pp.146-153. ISSN 0035-001X.

We examine quark flavour mixing matrices for three and four generations using the recursive parametrization of U(n) and SU(n) matrices developed earlier. After a brief summary of the recursive parametrization, we obtain expressions for the independent rephasing invariants and also the constraints on them that arise from the requirement of mod symmetry of the flavour mixing matrix.

Palavras-chave : Quark mixing matrix; recursive parametrization.
