  We use classical/large Nc (number of colors) QCD to study
nucleon--antinucleon annihilation at rest. We include pion, rho and omega
fields in the classical dynamics, starting from the nonlinear sigma model. We
begin with a spherical blob of pionic matter with zero baryon number and energy
of twice the nucleon mass. This evolves according to the classical dynamics to
pion and vector meson fields into the radiation zone. The radiation fields are
quantized using the method of coherent states modified to include isospin and
four momentum conservation. Empirical information is extracted from that
coherent state. We find good agreement with data for single particle momentum
and number spectra, and with branching ratios to many annihilation channels.
All this emerges with nearly no free parameters.
