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.

Long-lived biνo at the LHC

Journal Article Gehrlein, Julia ; Ipek, Seyda - Journal of High Energy Physics (Online)

We examine the detection prospects for a long-lived biνo, a pseudo-Dirac bino which is responsible for neutrino masses, at the LHC and at dedicated long-lived particle detectors. The biνo arises in U(1)_R-symmetric supersymmetric models where the neutrino masses are generated through higher dimensional operators in an inverse seesaw mechanism. At the LHC the biνo is produced through squark decays and it subsequently decays to quarks, charged leptons and missing energy via its mixing with the Standard Model neutrinos. We consider long-lived biνos which escape the ATLAS or CMS detectors as missing energy and decay to charged leptons inside the proposedmore »« less

Pseudo-Dirac bino dark matter

Journal Article Hsieh, Ken - Physical Review. D, Particles Fields

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 »« less

Naturally light Dirac and pseudo-Dirac neutrinos from left-right symmetry

Journal Article Babu, K. S. ; He, Xiao-Gang ; Su, Mingxian ; ... - Journal of High Energy Physics (Online)

We develop a class of left-right symmetric theories based on the gauge group SU(3)_c x SU(2)_L x SU(2)_R x U(1) with a generalized seesaw mechanism for generating the charged fermion masses. Neutrinos are naturally Dirac particles in this setup with their small masses arising from two-loop quantum corrections. We evaluate these two-loop diagrams exactly and analyze the flavor structure of the lepton sector. We find excellent fits to neutrino oscillation data, independent of the right-handed gauge symmetry breaking scale. We also explore the possibility that neutrinos are pseudo-Dirac particles in this framework, with the tiny mass splittings between active andmore »« less

Rare weak decays and direct lepton number violating signals in a minimal R-parity violating model of neutrino mass

Journal Article Datta, Amitava ; Saha, Jyoti Prasad ; Kundu, Anirban ; ... - Physical Review. D, Particles Fields

Within the framework of an R-parity violating minimal supergravity model, at least three relatively large lepton number violating {lambda}{sup '} type trilinear couplings at the grand unified theory scale, not directly related to neutrino physics, can naturally generate via renormalization group evolution and/or CKM rotation, the highly suppressed bilinear and trilinear parameters at the weak scale required to explain the neutrino oscillation data. The structure of the renormalization group equations and the CKM matrix restrict the choices of the three input couplings to only eight possible combinations, each with its own distinctive experimental signature. The relatively large input couplings maymore »« less

Addressing {mu}-b{sub {mu}} and proton lifetime problems and active neutrino masses in a U(1)'-extended supergravity model

Journal Article Hundi, R S ; Pakvasa, Sandip ; Tata, Xerxes - Physical Review. D, Particles Fields

We present a locally supersymmetric extension of the minimal supersymmetric standard model (MSSM) based on the gauge group SU(3){sub C}xSU(2){sub L}xU(1){sub Y}xU(1)' where, except for the supersymmetry-breaking scale which is fixed to be {approx}10{sup 11} GeV, we require that all non-standard-model parameters allowed by the local spacetime and gauge symmetries assume their natural values. The U(1)' symmetry, which is spontaneously broken at the intermediate scale, serves to (i) explain the weak scale magnitudes of {mu} and b{sub {mu}} terms, (ii) ensure that dimension-3 and dimension-4 baryon-number-violating superpotential operators (and, in a class of models, all {delta}B=1 operators) are forbidden, solvingmore »« less
