At best, DIS can only serve as an indirect test of QCD
by supplying asymptotic boundary conditions to be used in future non-perturbative QCD
calculations of the proton spin.
We calculate [PI] ([[PI].sub.[mu]]) employing the light cone QCD
sum rules (LCSR).
* A QCD
property called Asymptotic Freedom (see , p.
Some of the nonperturbative approaches to strongly interacting systems are the QCD
sum rules, quark models, and lattice QCD
Starting from the equation of motion in QCD
, they identify an invariant light front coordinate which allows separation of the dynamics of quark and gluon binding from the kinematics of constituent spin and internal orbital angular momentum.
Shipsey of Purdue University in West Lafayette, Ind., leader of a team using an accelerator at Cornell University to measure particle properties that will put the refined lattice QCD
to the test.
Now, apart from a supersymmetric extension, QCD
is not known for possessing any dual formulation and the full EL functional expressions certainly attest to this difficulty.
They're confident of the basic correctness of the current theory known as quantum chromodynamics, or QCD
. What may be in question, however, is the enterprise of extrapolating from the infinitesimal, quark-scale realm of QCD
to the experimentally measurable traits and behaviors of much larger particles, such as protons, neutrons, and mesons.
Due to the Debye screening of the Quantum Chromo-Dynamic (QCD
) potential between the two heavy quarks, quarkonia suppression was originally claimed to be an unambiguous signal of the formation of a quark-gluon plasma (QGP).
Overview topics included QCD
theory at large x, large-x resummations in QCD
, and MRST parton distributions.
Whatever the explanation, scientists are taking a second look at the theory of quantum chromodynamics, or QCD
, which describes the possible interactions of quarks.

In this regard, the Callan-Symanzik equation was fundamental to determine the asymptotic freedom of QCD
