Phenomenology of U(1)Lμ−Lτ charged dark matter at PAMELA/FERMI and colliders
نویسنده
چکیده
Recent data on e+/e− and p̄ cosmic rays suggest that dark matter annihilate into the standard model (SM) particles through new leptophilic interaction. In this paper, we consider a standard model extension with the gauged U(1)Lμ−Lτ group, with a new Dirac fermion charged under this U(1) as a dark matter. We study the muon (g − 2)μ, thermal relic density of the cold dark matter, and the collider signatures of this model. Z ′ productions at the Tevatron or the LHC could be easily order of O(1) −O(103) fb.

متن کاملGauged Lμ–Lτ with Large Muon Anomalous Magnetic Moment and the Bimaximal Mixing of Neutrinos
We consider the gauging of Lμ − Lτ as an explanation of a possibly large muon anomalous magnetic moment. We then show how neutrino masses with bimaximal mixing may be obtained in this framework. We study the novel phenomenology of the associated gauge boson in the context of present and future high-energy collider experiments. In the minimal standard model of quarks and leptons with no right-ha...
متن کاملVanishing Minors in the Neutrino Mass Matrix from Abelian Gauge Symmetries
Augmenting the Standard Model by three right-handed neutrinos allows for an anomaly-free gauge group extension Gmax = U(1)B−L × U(1)Le−Lμ × U(1)Lμ−Lτ . While simple U(1) subgroups of Gmax have already been discussed in the context of approximate flavor symmetries, we show how two-zero textures in the right-handed neutrino Majorana mass matrix can be enforced by the flavor symmetry, which is spo...
متن کاملAxinos in Cosmology and at Colliders
The axino, the fermionic superpartner of the axion, is a well-motivated candidate for cold dark matter if it is the lightest supersymmetric particle. Since the axino couples very weakly to the matter multiplets, the next-to-lightest supersymmetric particle (NLSP) has a long lifetime, which has important consequences for both cosmology and collider phenomenology. Assuming that a charged slepton ...
متن کاملNew Fixed-Target Experiments to Search for Dark Gauge Forces
Fixed-target experiments are ideally suited for discovering new MeV–GeV mass U(1) gauge bosons through their kinetic mixing with the photon. In this paper, we identify the production and decay properties of new light gauge bosons that dictate fixed-target search strategies. We summarize existing limits and suggest five new experimental approaches that we anticipate can cover most of the natural...
