Sum rules for B^0 - \bar B^0 mixing at NLO of pQCD
A. A. Pivovarov
The matrix element of B^0 -\bar B^0 mixing is evaluated from QCD sum rules for three-point correlators with next-to-leading order accuracy in pQCD.
Computing non-factorizable pQCD corrections to hadronic B^0 - \bar B^0 mixing matrix element within sum rules technique for three point Green functions
A. A. Pivovarov
In this talk I report on the results of a recent calculation of the α_s corrections to a three-point correlation function at the three-loop level in QCD perturbation theory, which…
Determination of the mass of the LambdaLambda dibaryon by the method of QCD sum rules
S. A. Larin, V. A. Matveev, A. A. Ovchinnikov +1
The method of QCD sum rules is used to calculate the mass of a hypothetical stable dihyperon H with the quantum numbers of two Lambda hyperons, whose existence was predicted by R.L…
Laurent series expansion of sunrise-type diagrams using configuration space techniques
S. Groote, J. G. Körner, A. A. Pivovarov
We show that configuration space techniques can be used to efficiently calculate the complete Laurent series \eps-expansion of sunrise-type diagrams to any loop order in D-dimensio…
