Title: Sizable NSI from the SU(2) L scalar doublet-singlet mixing and the implications in DUNE

Abstract

Here, we propose a novel and simple mechanism where sizable effects of non-standard interactions (NSI) in neutrino propagation are induced from the mixing between an electrophilic second Higgs doublet and a charged singlet. The mixing arises from a dimensionful coupling of the scalar doublet and singlet to the standard model Higgs boson. In light of the small mass, the light mass eigenstate from the doublet-singlet mixing can generate much larger NSI than those induced by the heavy eigenstate. We show that a sizable NSI ε (~0.3) can be attained without being excluded by a variety of experimental constraints. Furthermore, we demonstrate that NSI can mimic effects of the Dirac CP phase in the neutrino mixing matrix but they can potentially be disentangled by future long-baseline neutrino experiments, such as the Deep Underground Neutrino Experiment (DUNE).

  • The sphaleron structure in an SU(2) model with one Higgs doublet and one scalar singlet is examined. The sphaleron energy is numerically calculated as a function of the Higgs-boson mass and the self-coupling constant of the scalar field, and illustrative parameter configurations are also given.
  • We consider the phenomenological constraints on the mass {ital M}{sub {ital R}} and the {ital W}{sub {ital L}}-{ital W}{sub {ital R}} mixing angle {zeta} in a very general class of SU(2){sub {ital L}}{times}SU(2){sub {ital R}}{times}U(1) models. In particular, almost no model-dependent assumptions are made concerning left-right symmetry or the Higgs structure of the theory, which means that {ital U}{sup {ital R}}, the mixing matrix for right-handed quarks, is unrelated to the left-handed Cabibbo-Kobayashi-Maskawa matrix {ital U}{sup {ital L}}. We consider a number of possibilities for the neutrinos occurring in right-handed currents, including (a) heavy Majorana neutrinos, (b) heavy Dirac neutrinos,more » (c) intermediate-mass (10--100 MeV) neutrinos, and (d) light neutrinos (e.g., the Dirac partners of the ordinary left-handed neutrinos). For each case we utilize relevant constraints from the {ital K}{sub {ital L}}-{ital K}{sub {ital S}} mass difference, {ital B}{sub {ital d}}{bar B}{sub d} oscillations, the {ital b} semileptonic branching ratio and decay rate, neutrinoless double-beta decay, theoretical relations between mass and mixing, universality, nonleptonic kaon decays, muon decay, and astrophysical constraints from nucleosynthesis and SN 1987A. As is to be expected the limits on {ital M}{sub {ital R}} are considerably weaker than for the special case of manifest or pseudomanifest left-right symmetry ({ital M}{sub {ital R}}{gt}1.4 TeV). In fact, if extreme fine-tuning is allowed the {ital W}{sub {ital R}} could be as light as the ordinary {ital W}{sub {ital L}}. However, with reasonable restrictions on fine-tuning one obtains {ital M}{sub {ital R}}{gt}300 GeV for {ital g}{sub {ital R}}=g{sub L}, with more stringent limits holding for most of parameter space.« less
  • The authors discuss symmetry breaking and phenomenological aspects of rank 6 effective models in 4 dimensions, suggested by Calabi-Yau compactification of the heterotic E/sub 8/ x E/sub 8/ superstring, which have gauge group SU(3)/sub C/ x SU(2)/sub L/ x SU(2) x U(1)'. The simplest and most natural form of electroweak symmetry breaking for the softly broken effective SUSY theory is considered, and only those additions and alterations to the 27/sup 3/ based superpotential necessary to eliminate phenomenological problems are made. There are two physically distinct additional SU(2) factors, SU(2)/sub N/ and SU(2)/sub R/. The former has all gauge bosons electricallymore » neutral, the latter both charged and neutral. The additional SU(2) symmetry implies that large Dirac neutrino masses must be eliminated by a see-saw mechanism requiring the introduction of an E/sub 6/ singlet per generation and an intermediate scale of symmetry breaking M/sub I/(/ge/10/sup 10/ GeV). The intermediate scale symmetry breaking together with the couplings involving E/sub 6/ singlets needed for the see-saw mechanism unambiguously determines the form of the superpotential describing physics at low scales /approx/ 1 TeV. All additional heavy charge -1/3 quarks and additional Higgs doublets have masses /approx/ 1 TeV. An additional U(1)/sub E/ remains unbroken down to the 1 TeV scale. The resulting effective theories have no U(1)/sub E/ mediated FCNC due to mixing of heavy and light charge -1/3 quarks. Some couplings must be eliminated in order to prevent rapid nucleon decay.« less
  • An upper limit of 0.005 on the W/sub L/-W/sub R/ mixing angle in the SU(2)/sub L/ x SU(2)/sub R/ x U(1)= model is derived using semileptonic-decay data. This limit is possible because of the recent data on B decays, provided we assume only three generations.
