Query: Direct baryogenesis in the broken phase   We show a new mechanism for baryogenesis where the reheating temperature can
be smaller than the electroweak scale. The baryon number symmetry is violated
by a dimension nine operator which conserves a baryon parity. A high energy
quark from the decay of a heavy particle, $e.g.$ inflaton, modulus or
gravitino, undergoes flavor oscillation, and is thermalized due to the
scatterings with the ambient thermal plasma. We point out that the baryon
asymmetry of our universe can be generated due to the scatterings via the
baryon number violating operator. Our scenario can be tested in
neutron-antineutron oscillation experiments as well as other terrestrial
experiments.
