Anathematizing the Guralnik-Manohar bound for $\overline{\Lambda}$

There is a recent claim by Guralnik and Manohar \cite{GM} to have established a rigorous lower bound on $\bar \Lambda$, the asymptotic difference between the mass of a heavy flavour {\em hadron} and that of the heavy flavour {\em quark}. We point out the flaw in their reasoning and discuss the under...

description There is a recent claim by Guralnik and Manohar \cite{GM} to have established a rigorous lower bound on $\bar \Lambda$, the asymptotic difference between the mass of a heavy flavour {\em hadron} and that of the heavy flavour {\em 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.
