Three-loop HQET vertex diagrams for B0 - anti-B0 mixing
Dec, 2008Citations per year
Abstract: (arXiv)
Three-loop vertex diagrams in HQET needed for sum rules for B^0 - \bar{B}^0 mixing are considered. They depend on two residual energies. An algorithm of reduction of these diagrams to master integrals has been constructed. All master integrals are calculated exactly in d dimensions; their epsilon expansions are also obtained.Note:
