| ABSTRACT: |
Observation of neutron-antineutron oscillations would constitute a discovery of fundamental
importance. It requires B violation by 2 units and therefore probes different physics from proton decay.
B violation is needed in Sakharov mechanism to generate the baryon asymmetry of the universe in the Big Bang.
I will review the scientific motivation to search for B violation, describe present limits on deltaB=2 processes,
and describe two possible experimental approaches to improve the present limits: one using cold neutrons, another using ultracold neutrons.
