Abstract

We show that experimental probes of the P-conserving, T-violating triple correlation in polarized neutron or nuclear β-decay provide a unique probe of possible T-violation at the TeV scale in the presence of right-handed neutrinos. In contrast to other possible sources of semileptonic T-violation involving only left-handed neutrinos, those involving right-handed neutrinos are relatively unconstrained by present limits on the permanent electric dipole moments of the electron, neutral atoms, and the neutron. On the other hand, LHC results for pp→e+ missing transverse energy imply that an order of magnitude of improvement in D-coefficient sensitivity would be needed for discovery. Finally, we discuss the interplay with the scale of neutrino mass and naturalness considerations.

Detection of heavy Majorana neutrinos and right-handed bosons

Journal Article Gninenko, S N ; Kirsanov, M M ; Krasnikov, N V ; ... - Physics of Atomic Nuclei

The SU{sub c}(3) - SU{sub L}(2) - SU{sub R}(2) - U(1) left-right (LR) symmetric model explains the origin of the parity violation in weak interactions and predicts the existence of additional gauge bosons W{sub R} and Z'. In addition, heavy right-handed Majorana neutrino states N arise naturally within the LR symmetric model. The states N could be partners of light neutrino states, related to their nonzero masses through the seesaw mechanism. This makes the searches for W{sub R}, Z', and N interesting and important. In the framework of the minimal LR model, we study the possibility to observe signals frommore »« less

One-loop contribution to the neutrino mass matrix in the next-to-minimal supersymmetric standard model with right-handed neutrinos and tribimaximal mixing

Journal Article Das, Debottam ; Roy, Sourov ; Department of Theoretical Physics and Centre for Theoretical Sciences, Indian Association for the Cultivation of Science, 2A and 2B Raja S.C. Mullick Road, Kolkata 700 032 - Physical Review. D, Particles Fields

Neutrino mass patterns and mixing have been studied in the context of the next-to-minimal supersymmetric standard model (NMSSM) with three gauge singlet neutrino superfields. We consider the case with the assumption of R-parity conservation. The vacuum expectation value of the singlet scalar field S of NMSSM induces the Majorana masses for the right-handed neutrinos as well as the usual {mu} term. The contributions to the light neutrino mass matrix at the tree level as well as one-loop level are considered, consistent with the tribimaximal pattern of neutrino mixing. Light neutrino masses arise at the tree level through a TeV-scale seesawmore »« less

Probing right handed neutrinos at the LHeC and lepton colliders using fat jet signatures

Journal Article Das, Arindam ; Jana, Sudip ; Mandal, Sanjoy ; ... - Physical Review D

The inclusion of heavy neutral leptons (right-handed neutrinos) to the Standard Model (SM) particle content is one of the best motivated ways to account for the observed neutrino masses and flavor mixing. The modification of the charged and neutral currents from active-sterile mixing of the neutral leptons can provide novel signatures which can be tested at the future collider experiments. In this article, we explore the discovery prospect of a very heavy right handed neutrino to probe such extensions at the future collider experiments like Large Hadron electron Collider (LHeC) and linear collider. We consider the production of the heavymore »« less

Inclusive charged current neutrino reactions: implications for gauge models with heavy quarks and right-handed currents. [Total cross sections, Weinberg-Salam, vector, and six-quark models, parity violation]

Conference Albright, C H ; Shrock, R E

The predictions of several gauge theory models for deep inelastic neutrino reactions on both isoscalar and proton targets are analyzed. In particular, y and W distributions, mean values of various kinematic quantities, and total cross sections are calculated. The effects of heavy quark production and the possible excitation of right-handed currents are discussed. In addition to the Weinberg-Salam and vector models, one studies certain six-quark models which have parity-violating neutral currents. Estimates of effective heavy quark masses are presented for each model.
Probing neutrino Dirac mass in left-right symmetric models at the LHC and next generation colliders

Journal Article Helo, Juan Carlos ; Li, Haolin ; Neill, Nicolás A. ; ... - Physical Review D

We assess the sensitivity of the LHC, its high energy upgrade, and a prospective 100 TeV hadronic collider to the Dirac Yukawa coupling of the heavy neutrinos in left-right symmetric models (LRSMs). We focus specifically on the trilepton final state in regions of parameter space yielding prompt decays of the right-handed gauge bosons (W_R) and neutrinos (N_R). In the minimal LRSM, the Dirac Yukawa couplings are completely fixed in terms of the mass matrices for the heavy and light neutrinos. In this case, the trilepton signal provides a direct probe of the Dirac mass term for a fixed W_R andmore »« less
