    Sammanfattning : This thesis treats neutron-antineutron oscillations in the framework of chiral perturbation theory. An effective Lagrangian, using mesons and nucleons as degrees of freedom, is constructed to capture the low-energy behavior of the effective six-quark operators, which is the set of higher dimensional operators that can induce neutron to antineutron transitions at the quark level.
