We investigate a model in which tiny neutrino masses are generated at the two-loop level by using scalar leptoquark and diquark multiplets. The diquark can be singly produced at the LHC, and it can decay into a pair of leptoquarks through the lepton number violating interaction. Subsequent decays of the two leptoquarks can provide a clear signature of the lepton number violation, namely two QCD jets and a pair of same-signed charged leptons without missing energy. We show that the signal process is not suppressed while neutrino masses are appropriately suppressed.
We study the observability for a heavy Majorana neutrino N along with a new charged gauge boson W at the LHC. We emphasize the complementarity of these two particles in their production and decay to unambiguously determine their properties. We show t
We propose a simple left-right symmetric theory where the neutrino masses are generated at the quantum level. In this context the neutrinos are Majorana fermions and the model has the minimal degrees of freedom in the scalar sector needed for symmetr
Some models of leptogenesis involve a nearly-degenerate pair of heavy Majorana neutrinos $N_{1,2}$ whose masses can be small, $O({rm GeV})$. There can be heavy-light neutrino mixing parametrized by $|B_{ell N}|^2 = 10^{-5}$, which leads to the rare l
Some models of leptogenesis involve a quasi-degenerate pair of heavy neutrinos $N_{1,2}$ whose masses can be small, $O({rm GeV})$. Such neutrinos can contribute to the rare lepton-number-violating (LNV) decay $W^pm to ell_1^pm ell_2^pm (q{bar q})^mp$
We study lepton flavour violating decays of neutralinos and sleptons within the Minimal Supersymmetric Standard Model, assuming two and three generation mixings in the slepton sector. We take into account the most recent bounds on flavour violating r
