Abstract
In this talk I shall discuss how a search for
neutron-antineutron
oscillations can be carried out at the European
Spallation Source. It will
be shown how such oscillations can provide a unique
probe of some of the
central questions in particle physics and cosmology:
the energy scale and
mechanism for baryon number violation, the origin of
the baryon-antibaryon
asymmetry of the universe, and the mechanism for
neutrino mass generation.
An overview of the proposed experiment and its
capability to a sensitivity
to the oscillation probability, which is three
orders of magnitude greater
than previously obtained, will be given. The
international collaboration
which has been formed to carry out the proposed work
will also be
described.
