Title: Neutrino masses from a pseudo-Dirac bino

Abstract

We show that, in U(1) R-symmetric supersymmetric models, the bino and its Dirac partner (the singlino) can play the role of right-handed neutrinos and generate the neutrino masses and mixing, without the need for traditional bilinear or trilinear R-parity violating operators. The two particles form a pseudo-Dirac pair, the “bi νo.” An inverse seesaw texture is generated for the neutrino-biνo sector, and the lightest neutrino is predicted to be massless. Lastly, unlike in most models with heavy right-handed neutrinos, the bi νo can be sizably produced at the LHC through its interactions with colored particles, while respecting low energy constraints from neutrinoless double-beta decay and charged lepton flavor violation.

  • While the bino-dominated lightest neutralino of the minimal supersymmetric standard model (MSSM) is an interesting and widely studied candidate of dark matter, the p-wave suppression of its annihilation cross section requires fine-tuning of the MSSM spectra to be consistent with Wilkinson Microwave Anisotropy Probe (WMAP) observations. We propose a pseudo-Dirac bino that arises in theories with D-type supersymmetry breaking as an intriguing alternative candidate of dark matter. The pseudo-Dirac nature of the bino gives a natural mechanism of enhanced coannihilation because these two states are degenerate in the absence of electroweak symmetry breaking. In addition, the lightest state can bemore » consistent with limits of direct-detection experiments because of the lack of vector interactions, as with the case of the MSSM bino.« less
  • We present a scenario of neutrino masses and mixing angles. Each generation includes a sterile right-handed neutrino in addition to the usual left-handed one. We assume a hierarchy in their Dirac masses similar to, but much larger than, the hierarchies in the quarks and charged leptons. In addition, we include a Majorana mass term for the sterile neutrinos only. These assumptions prove sufficient to accommodate scales of mass differences and mixing angles consistent with all existing neutrino oscillation data. {copyright} {ital 1997} {ital The American Physical Society}
  • Certain superstring theories contain new exotic particles and couplings active at low energies. We show that they offer a solution to a long-standing problem simultaneously having naturally small Dirac neutrino masses and vanishing Majorana masses. It is therefore consistent with (a) a lack of observation of neutrinoless double ..beta.. decay, (b) a possible evidence for nonvanishing neutrino mass, and (c) a recently proposed solution to the solar neutrino problem.
  • We derive new bounds on the Dirac mass of the tau and muonic neutrinos. By solving the kinetic equation for the rate of energy deposition due to helicity-flipping processes and imposing the constraint that the number of effective species contributing to the energy density at the time of nucleosynthesis be [Delta][ital k][sub [nu]][lt]0.3, we find the bounds [ital m][sub [nu][mu]][lt]150 keV and [ital m][sub [nu][tau]][lt]190 keV for [ital T][sub QCD]=200 MeV. The constraint [Delta][ital k][sub [nu]][lt]0.1 leads to the much stronger bound [ital m][sub [nu]][lt]10 keV for both species of neutrinos.
