We show that left-right symmetric models can easily accommodate stable TeV-scale dark matter particles without the need for an ad hoc stabilizing symmetry. The stability of a newly introduced multiplet either arises accidentally as in the minimal dark matter framework or comes courtesy of the remaining unbroken Z2 subgroup of B-L. Only one new parameter is introduced: the mass of the new multiplet. As minimal examples, we study left-right fermion triplets and quintuplets and show that they can form viable two-component dark matter. This approach is, in particular, valid for SU(2)×SU(2)×U(1) models that explain the recent diboson excess at ATLAS in terms of a new charged gauge boson of mass 2 TeV. © 2015 American Physical Society. © 2015 American Physical Society.

Majority of the plant disease resistance genes expresses cytoplasmic receptor-like proteins characterized by an N-terminal nucleotide-binding site (NBS) and a leucine-rich repeat (LRR) domain. Degenerative primers based on these conserved motifs were used to isolate NBS type sequences in Kaempferia galanga. Cloning and sequencing identified 12 Kaempferia NBS-type sequences called resistance gene candidates (RGCs) classified into four classes. The amino acid sequences of the RGCs detected the presence of conserved domains, viz., kinase-1a, kinase-2, and hydrophobic GLPL, categorizing them with the NBS-LRR class gene family. Structural and phylogenetic characterization grouped the RGCs with the non-toll interleukin receptor (non-TIR) subclasses of the NBS sequences. Reverse transcription PCR with 10 Kaempferia RGC specific primers revealed 7 out of 10 Kaempferia RGCs to be expressive. The isolation and characterization of Kaempferia RGCs has been reported for the first time in this study. This will provide a starting point towards characterization of candidate resistance genes in Kaempferia and can act as a source pool for disease resistance development in other asexually reproducing plants.

We present an alternative formulation of the left-right symmetric theory where the scalar sector consists of two Higgs doublets. This formulation differs from the standard version of the left-right model that makes use of L- and R- Higgs triplets and a Higgs bidoublet. The basic idea is to consider a few extra charged isosinglet fields; the fermion masses can be realized by integrating out these heavy isosinglet fields. We also give a detailed discussion on neutrinoless double beta decay in this particular left-right symmetric theory where the right-handed (RH) Majorana neutrino can be of MeV range. With this RH Majorana mass around the MeV scale, the contribution to neutrinoless double beta decay coming from the right-handed current can be comparable to the contributions coming from the standard left-handed sector only if the right-handed gauge boson mass is around 5 TeV. With this operative scale of WR around a few TeV, it is possible to probe at the LHC. We have briefly commented on cosmological constraints from the big-bang nucleosynthesis and Universe cosmology on the RH neutrinos involved in this discussion. © 2013 American Physical Society.

This paper proposes a new scheme for measurement, identification, and classification of various types of power quality (PQ) disturbances. The proposed method employs a fast variant of S-Transform (ST) algorithm for the extraction of relevant features, which are used to distinguish among different PQ events by a fuzzy decision tree (FDT)-based classifier. Various single as well as simultaneous power signal disturbances have been simulated to demonstrate the efficiency of the proposed technique. The simulation result implies that the proposed scheme has a higher recognition rate while classifying simultaneous PQ faults, unlike other methods. The Fast dyadic S-transform (FDST) algorithm for accurate time-frequency localization, Decision Tree algorithms for optimal feature selection, Fuzzy decision rules to complement overlapping patterns, robust performance under different noise conditions and a relatively simple classifier methodology are the strengths of the proposed scheme. © 2013 IEEE.

Recently realization of TeV scale inverse seesaw mechanism in supersymmetric SO(10) framework has led to a number of experimentally verifiable predictions including low-mass WR± and Z ′ gauge bosons and nonunitarity effects. Using nonsupersymmetric SO(10) grand unified theory, we show how a TeV scale inverse seesaw mechanism for neutrino masses is implemented with a low-mass Z ′ boson accessible to Large Hadron Collider. We derive renormalization group equations for fermion masses and mixings in the presence of the intermediate symmetries of the model and extract the Dirac neutrino mass matrix at the TeV scale from successful grand unified theory-scale parametrization of fermion masses. We estimate leptonic nonunitarity effects measurable at neutrino factories and lepton flavor violating decays expected to be probed in the near future. While our prediction on the nonunitarity matrix element η μτ for degenerate right-handed neutrinos is similar to the supersymmetric SO(10) case, we find new predictions with significantly enhanced value of its phase δ μτ10 -4-10 -2 when partial degeneracy among these neutrino masses is adequately taken into account by a constraint relation that emerges naturally in this approach. Other predictions on branching ratios and CP-violating parameters are discussed. An important distinguishing characteristic as another test of the minimal model is that the threshold corrected two-loop prediction of the proton lifetime with maximum value (τ p) maxa1035yrs. is accessible to ongoing search experiments for the decay p→e +π0 in the near future. Simple model extensions with longer proton lifetime predictions are also discussed. © 2012 American Physical Society. Source
