  The detection of neutron-antineutron oscillation will be a discovery of
fundamental importance in particle physics and cosmology. In models discussed
widely in literature, the process is generated through heavy New Physics with
weak, perturbative, coupling at the scale of the experiment. Acknowledging the
fact that Nature has been quite evasive regarding the strength and scale of New
Physics, we discuss a new mechanism, generated by confining New Physics, at
$\sim 2$ GeV, resulting in low-energy baryon number violating effects. The
mechanism predicts baryon number violating processes like neutron
disappearance, neutron-neutron annihilation and neutron-anti neutron
oscillation generated through the condensation of the linear moose.
