A Simple Model of Neutrino Masses from Supersymmetry Breaking
We analyze a class of supersymmetric models first introduced by Arkani-Hamed et al and Borzumati et al in which the light neutrino masses result from higher-dimensional supersymmetry-breaking terms in the MSSM superand Kahler-potentials. The mechanism is closely related to the Giudice-Masiero mechanism for the MSSM μ parameter, and leads to TeV-scale right-handed neutrino and sneutrino states, ...
متن کاملSmall Neutrino Masses from Supersymmetry Breaking
An alternative to the conventional see-saw mechanism is proposed to explain the origin of small neutrino masses in supersymmetric theories. The masses and couplings of the right-handed neutrino field are suppressed by supersymmetry breaking, in a way similar to the suppression of the Higgs doublet mass, μ. New mechanisms for light Majorana, Dirac and sterile neutrinos occur, depending on the de...
متن کاملDirac neutrino masses from generalized supersymmetry breaking.
We demonstrate that Dirac neutrino masses in the experimentally preferred range are generated within supersymmetric gauge extensions of the standard model with a generalized supersymmetry breaking sector. If the superpotential neutrino Yukawa terms are forbidden by the gauge symmetry [such as a U(1)'], sub-eV scale effective Dirac mass terms can arise at tree level from hard supersymmetry break...
متن کاملSupersymmetry and Neutrino Masses
Neutrino masses are zero in the minimal supersymmetric standard model. I discuss how they may become nonzero with new interactions which may or may not violate R-parity conservation. ———————– Talk presented at the 6th Corfu Summer Institute on Elementary Particle Physics, 1998.
متن کاملDynamical Supersymmetry Breaking from Simple Quivers
We construct a simple local model of dynamical supersymmetry breaking. The model is a one generation SU(5) that arises from a IIB ZN orientifold. It does not admit a runaway direction and is argued to stabilize the blowup mode related to the corresponding U(1) factor. The theory demonstrates the existence of a new class of “blowup” fractional branes. We further discuss a compact realization of ...
