Anathematizing the Guralnik and Manohar Inequality for Λ

Original · EN

There is a recent claim by Guralnik and Manohar GM to have established a rigorous lower bound on Λ, the asymptotic difference between the mass of a heavy flavour hadron and that of the heavy flavour quark. We point out the flaw in their reasoning and discuss the underlying physical problem. An explicit counterexample to the GM bound is given; one can therefore not count on a refined proof to re-establish this bound. *********** Uses LaTeX No figures No macros file used.
