Abstract
We argue that different aspects of light-front QCD at the confined
phase can be recovered by the matrix quantum mechanics of D0-branes.
The relevant matrix quantum mechanics is obtained from dimensional
reduction of pure Yang-Mills theory to dimension 0+1. The
aspects of
QCD dynamics which are studied in correspondence with D0-branes
are:
(1) phenomenological inter-quark potentials, (2) the
whiteness of hadrons
and (3) scattering amplitudes. In addition, some other issues
such as the
large-N behavior, the gravity-gauge theory relation and also
a
possible justification for involving "non-commutative coordinates"
in the study of QCD bound states are discussed.
