Observable Seesaw and its Collider Signatures
We discuss the scenario with TeV-scale right-handed neutrinos, which are accessible at future colliders, while holding down tiny seesaw-induced masses and sizable couplings to the standard-model particles. The signal with tri-lepton final states and large missing transverse energy is appropriate for studying collider signatures of the scenario with extra spatial dimensions. We show that the LHC...
متن کاملSupersymmetric Models and Collider Signatures
We briefly review the SUGRA, GMSB and AMSB supersymmetry breaking models. We then discuss the phenomenological differences between them and consequent characteristic experimental signatures. This is followed by a review of the discovery potential for supersymmetry at the Tevatron, LHC and a future ee linear collider.
متن کاملObservable Neutron–Antineutron Oscillations in Seesaw Models of Neutrino Mass
We show that in a large class of supersymmetric models with spontaneously broken B − L symmetry, neutron–antineutron oscillations occur at an observable level even though the scale of B − L breaking is very high, vB−L ∼ 2 × 10 16 GeV, as suggested by gauge coupling unification and neutrino masses. We illustrate this phenomenon in the context of a recently proposed class of seesaw models that so...
متن کاملSeesaw Mechanism and Its Implications
The seesaw mechanism is introduced and some of its different realizations and applications are discussed. It is pointed out how they can be used to understand the bi-large mixing patterns among neutrinos in combination with the assumptions about high scale physics such as grand unification or quasidegeneracy of neutrino masses.
متن کاملObservable (?) cosmological signatures of superstring models
The different couplings of the dilaton to the U(1) gauge field of heterotic and Type I superstrings may leave an imprint on the relics of the very early cosmological evolution. We discuss the possibility of discriminating between the two models through cross-correlated observations of cosmic magnetic fields and primordial gravitationalwave backgrounds. CERN-PH-TH/2005-216 November 2005 It is we...
