New extended Crewther-type relation and the consequences of multiloop perturbative results
A. L. Kataev, S. V. Mikhailov
We discuss the current status of the investigations of the conformal symmetry breaking contributions to three forms for the QCD generalizations of the Crewther relation. The new th…

New extended Crewther-type relation
A. L. Kataev, S. V. Mikhailov
We propose a conjecture about the detailed structure of the conformal symmetry breaking term in the generalized Crewther relation. We conclude that this conjecture leads to new rel…
