Interference between light and heavy neutrinos for 0 νββ decay in the left–right symmetric model
Abstract
Neutrinoless doublebeta decay is proposed as an important low energy phenomenon that could test beyond the Standard Model physics. There are several potentially competing beyond the Standard Model mechanisms that can induce the process. It thus becomes important to disentangle the different processes. In the present study we consider the interference effect between the light lefthanded and heavy righthanded Majorana neutrino exchange mechanisms. The decay rate, and consequently, the phasespace factors for the interference term are derived, based on the left–right symmetric model. The numerical values for the interference phasespace factors for several nuclides are calculated, taking into consideration the relativistic Coulomb distortion of the electron wave function and finitesize of the nucleus. As a result, the variation of the interference effect with the Qvalue of the process is studied.

Search for Heavy Neutrinos and ${W}_{R}$ Bosons with RightHanded Couplings in a LeftRight Symmetric Model in $pp$ Collisions at $\sqrt{s}=7\text{}\text{}\mathrm{TeV}$
Results are presented from a search for heavy, righthanded muon neutrinos, N[mu], and righthanded W[R] bosons, which arise in the leftright symmetric extensions of the standard model. The analysis is based on a 5.0 inverse femtobarn sample of protonproton collisions at a centerofmass energy of 7 TeV, collected by the CMS detector at the Large Hadron Collider. No evidence is observed for an excess of events over the standard model expectation. For models with exact leftright symmetry, heavy righthanded neutrinos are excluded at 95% confidence level for a range of neutrino masses below the W[R] mass, dependent on the valuemore » 
Leftright SU(3){sub L}xSU(3){sub R}xU(1){sub X} model with light, keV, and heavy neutrinos
We construct a full leftright model for the electroweak interactions based on the SU(3){sub L} x SU(3){sub R} x U(1){sub X} gauge symmetry. The fermion content of the model is such that anomaly cancellation restricts the number of families to be a multiple of three. One of the most important features of the model is the joint presence of three light active neutrinos, three additional neutrinos at keV mass scale, and six heavy ones with masses around 10{sup 11} GeV. They form a wellmotivated part of the spectrum in the sense that they address challenging problems related to neutrino oscillation,more » 
Double seesaw mechanism in a leftright symmetric model with TeV neutrinos
A leftright symmetric model is discussed with new mirror fermions and a Higgs sector with two doublets and neutral scalar singlets. The seesaw mechanism is generalized, including not only neutrino masses but also charged fermion masses. The spectrum of heavy neutrinos presents a second seesaw mass matrix and has neutrinos masses naturally in the TeV region. The model has very clear signatures for the new neutral vector gauge bosons. Two classes of models are discussed. New mirror neutrinos can be very light and a new Z{sup '} can be discriminated from other models by a very high invisible branching fraction.more » 
[ital K][sub [ital L]][ital K][sub [ital S]], [ital B][sub [ital d]][sup 0][ital [bar B]][sub [ital d]][sup 0] mass differences and [ital t]quark and [ital W][sub [ital R]]boson masses in the leftrightsymmetric model
An SU(2)[sub [ital L]][direct product]SU(2)[sub [ital R]][direct product]U(1)[sub [ital B][minus][ital L]] effective Hamiltonian is considered to estimate the masses of the [ital t] quark and [ital W][sub [ital R]] boson. Taking SU(6)symmetric ([ital K][sup 0],[ital [bar K]][sup 0]) and ([ital B][sub [ital d]][sup 0],[ital [bar B]][sub [ital d]][sup 0]) mesonic states in a fieldtheoretic quark model, we evaluate the hadronic matrix elements with the help of [ital W][sub [ital L]][ital W[ital R]] box diagrams and obtain the [ital K][sup 0][ital [bar K]0] and [ital B][sub [ital d]][sup 0][ital [bar B]][sub [ital d]][sup 0] mass differences.
