Title: Renormalization effects on neutrino masses and mixing in a string-inspired SU(4)xSU(2){sub L}xSU(2){sub R}xU(1){sub X} model

Abstract

We discuss renormalization effects on neutrino masses and mixing angles in a supersymmetric string-inspired SU(4)xSU(2){sub L}xSU(2){sub R}xU(1){sub X} model, with matter in fundamental and antisymmetric tensor representations and singlet Higgs fields charged under the anomalous U(1){sub X} family symmetry. The quark, lepton and neutrino Yukawa matrices are distinguished by different Clebsch-Gordan coefficients. The presence of a second U(1){sub X} breaking singlet with fractional charge allows a more realistic, hierarchical light neutrino mass spectrum with bi-large mixing. By numerical investigation we find a region in the model parameter space where the neutrino mass-squared differences and mixing angles at low energy are consistent with experimental data.

  • We consider an extension of the standard model gauge symmetry to a local gauge group SU(3){sub C}xSU(3){sub L}xU(1){sub X} which is a subgroup of SU(4){sub PS}xSU(4){sub L+R}. The symmetry breaking pattern is SU(4){yields}SU(3)xU(1) for both weak SU(4){sub L+R} and strong Pati-Salam SU(4){sub PS} group. The SU(3){sub C}xU(1){sub B-L}xSU(3){sub L}xU(1){sub Y1} (3-3-1-1) local gauge symmetry breaks to SU(3){sub C}xSU(3){sub L}xU(1){sub X} and generates a 3-3-1 model with three-generation, anomaly-free fermions which transform as bifundamentals of (3-3-1-1). The 3-3-1 model is of Pleitez-Frampton type but SU(3){sub L} gauge bosons (B-L=0) do not include bilepton gauge boson. The neutral gauge bosons include {gamma},Z,Z{supmore » '} and a fourth, heavy gauge boson Z{sup ''} which decouples from rest but can decay to ordinary fermions. An analysis for two-body decays of neutral Z{sup '} gauge boson is presented. From Yukawa interactions, the masses of all exotic fermions are obtained in the TeV region. This restricts Z{sup '} decays to exotic fermions. The Z{sup '} is also found to be leptophobic and decays mainly to quarks.« less
  • We consider various possibilities for generating neutrino masses in supersymmetric models with an additional U(1){sup '} gauge symmetry. One class of models involves two extra U(1){sup '}xU(1){sup ''} gauge symmetries, with U(1){sup ''} breaking at an intermediate scale and yielding small Dirac masses through high-dimensional operators. The right-handed neutrinos N{sub i}{sup c} can naturally decouple from the low energy U(1){sup '}, avoiding cosmological constraints. A variant version can generate large Majorana masses for N{sub i}{sup c} and an ordinary seesaw. We secondly consider models with a pair of heavy triplets which couple to left-handed neutrinos. After integrating out the heavymore » triplets, a small neutrino Majorana mass matrix can be generated by the induced nonrenormalizable terms. We also study models involving the double-seesaw mechanism, in which heavy Majorana masses for N{sub i}{sup c} are associated with the TeV-scale of U(1){sup '} breaking. We give the conditions to avoid runaway directions in such models and discuss simple patterns for neutrino masses.« less
  • SU(2)/sub L/xSU(2)/sub R/xU(1)/sub B/-L models with Majorana neutrinos are reexamined neglecting neutrino mixing. Careful analysis shows that values of the left-right mixing angle larger than those obtained by previous authors are permitted by experimental data. As a consequence lower values of charged- and neutral-gauge-boson masses are permissible. The recent bounds on M/sub W/ from the CERN p-barp collider further restrict the allowed ranges of the parameters obtained from neutral-current data fits.
  • In the known fermions transform under SU(2)/sub L/xSU(2)/sub R/xU(1)/sub B/-L, then the two neutral vector gauge bosons must satisfy the bounds 83 GeV200 GeV. In addition, if mixing is negligible for the two charged vector gauge bosons, then 75 GeV
  • We investigate a simple model of neutrino mass based on SU(3){sub C}xSU(3){sub L}xU(1){sub X} gauge unification. The Yukawa coupling of the model has automatic lepton-number symmetry which is broken only by the self-couplings of the Higgs boson. At tree level, the neutrino spectrum contains three Dirac fermions, one massless and two degenerate in mass. At the two-loop level, neutrinos obtain Majorana masses and correct the tree-level result which naturally gives rise to an inverted hierarchy mass pattern and interesting mixing which can fit the current data with minor fine-tuning. In another scenario, one can pick the scales such that themore » loop-induced Majorana mass matrix is bigger than the Dirac one and thus reproduces the usual seesaw mechanism.« less
