  We present first results from a new parton shower event generator, Deductor.
Anticipating a need for an improved treatment of parton color and spin, the
structure of the generator is based on the quantum density matrix in color and
spin space. So far, Deductor implements only a standard spin-averaged treatment
of spin in parton splittings. Although Deductor implements an improved
treatment of color, in this paper we present results in the standard leading
color approximation so that we can compare to the generator Pythia. The
algorithms used incorporate a virtuality based shower ordering parameter and
massive initial state bottom and charm quarks.
