Renormalization effects on neutrino masses and mixing in a stringinspired 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 stringinspired 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 ClebschGordan 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 bilarge mixing. By numerical investigation we find a region in the model parameter space where the neutrino masssquared 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 PatiSalam SU(4){sub PS} group. The SU(3){sub C}xU(1){sub BL}xSU(3){sub L}xU(1){sub Y1} (3311) local gauge symmetry breaks to SU(3){sub C}xSU(3){sub L}xU(1){sub X} and generates a 331 model with threegeneration, anomalyfree fermions which transform as bifundamentals of (3311). The 331 model is of PleitezFrampton type but SU(3){sub L} gauge bosons (BL=0) do not include bilepton gauge boson. The neutral gauge bosons include {gamma},Z,Z{supmore »

Neutrino masses in supersymmetric SU(3){sub C}xSU(2){sub L}xU(1){sub Y}xU(1){sup '} models
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 highdimensional operators. The righthanded 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 lefthanded neutrinos. After integrating out the heavymore » 
Leftright mixing in SU(2)/sub L/xSU(2)/sub R/xU(1)/sub B/L gauge models and weakinteraction phenomenology
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 leftright mixing angle larger than those obtained by previous authors are permitted by experimental data. As a consequence lower values of charged and neutralgaugeboson masses are permissible. The recent bounds on M/sub W/ from the CERN pbarp collider further restrict the allowed ranges of the parameters obtained from neutralcurrent data fits. 
Bounds on M/sub Z//sub 1,2/ in any SU(2)/sub L/xSU(2)/sub R/xU(1)/sub B/L gauge model
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 
Interesting radiative patterns of neutrino mass in an SU(3){sub C}xSU(3){sub L}xU(1){sub X} model with righthanded neutrinos
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 leptonnumber symmetry which is broken only by the selfcouplings of the Higgs boson. At tree level, the neutrino spectrum contains three Dirac fermions, one massless and two degenerate in mass. At the twoloop level, neutrinos obtain Majorana masses and correct the treelevel result which naturally gives rise to an inverted hierarchy mass pattern and interesting mixing which can fit the current data with minor finetuning. In another scenario, one can pick the scales such that themore »
