On the Quark Kinetic Energy in the
We consider the problem of determining the matrix element of the heavy quark
kinetic energy operator between baryonic states by three point
function QCD sum rules in the Heavy Quark Effective Theory. We discuss the main
features and the uncertainties associated to such an approach. Numerically, we
find the result: . Within the uncertainty of the method, such result indicates a value of
the heavy quark kinetic energy in the baryon similar in size to that in the
meson.Comment: RevTex, 13 pages + 3 uuencoded figures. Figures and comments on high
