  I will discuss the gap and Bethe-Salpeter equations for quantum
chromodynamics in Coulomb gauge under a leading order truncation scheme. Within
this scheme, the role of charge conservation and the cancellation of infrared
divergences becomes particularly clear. The quark gap equation exhibits not
only chiral symmetry breaking, but explicitly reproduces the heavy quark limit.
The corresponding gluon equation has a massive solution with interesting
nonperturbative renormalization properties. I will further discuss various
aspects of the Bethe-Salpeter equation for pseudoscalar and vector mesons with
arbitrary quark masses and present numerical results for the meson masses and
leptonic decay constants.
