Scalar Correlator at O(alpha_s^4), Higgs Decay into b-quarks and Bounds on the Light Quark Masses
P. A. Baikov, K. G. Chetyrkin, J. H. Kühn
We compute, for the first time, the absorptive part of the massless correlator of two quark scalar currents in five loops. As physical applications we consider the O(alpha_s^4) cor…

A practical criterion of irreducibility of multi--loop Feynman integrals
P. A. Baikov
A practical criterion for the irreducibility (with respect to integration by part identities) of a particular Feynman integral to a given set of integrals is presented. The irreduc…
