Abstract

Neutrinos violate CPT symmetry within our universe, thus providing an asymmetry between neutrinos and antineutrinos. Is the Lightest Kaluza-Klein Particle (LKP) the right-handed neutrino? We discuss possible solutions to the problem by introducing Supersymmetry and an extra-dimensional Kaluza-Klein Model. Assuming gravitinos are Majorana particles, we use the existence of neutrino-less double beta decay to create a Feynman diagram for both the Gravitino Interaction and the LKP. We then compare the Gravitino LSP and the LKP models.The Neutralino and Gravitino are SUSY Majorana particles that are strong candidates for dark matter, along with the LKP. We take the current model considering Gravitinos as the LSP and Neutralinos as the NLSP and add a LKP interaction to explain dark matter in our universe. Our efforts unify the Standard Model, the SUSY extension of the Standard Model, and the Kaluza-Klein Model, where the LSP Gravitino resides in the extra dimension and the LKP is the right-handed neutrino. We wish to scale our work unifying SUSY and LKP in our quest of finding not only a mirror particle but a mirror universe, in the same vein as Boyle, et al, in our grand hope of becoming an interstellar civilization.
