[net.physics] Quark binding energies

emh@bonnie.UUCP (Edward M. Hummel) (06/19/85)

	Here is a little question for the quantum field theory-
quantum chromodynamics guys.  Consider a typical meson, which is
made up of two quarks (q,qbar).  The meson has a mass, and I assume
that the quarks have a definite mass (after some kind of
renormalization, perhaps).  Energy conservation would indicate
that:

	(meson mass) = (q mass) + (qbar mass) - (binding energy)

Now for the question.  How does one define the binding energy
of quarks in hadrons?  The classical notion of "binding energy" is
defined in terms of the potential when the objects are
infinitely separated.  What does that mean for q and qbar?
If the binding energy is infinite, what does this imply about
the mass of our meson?
