Neutrino Decays and Neutrino Electron Elastic Scattering in Unparticle Physics
Following Georgi’s unparticle scheme, we examine the effective couplings between neutrinos and unparticle operators. As an immediate consequence, neutrinos become unstable and can decay into the unparticle stuff. Assuming the dimension transmutation scale is around ΛU ∼ 1 TeV, we implement the cosmological limit on the neutrino lifetime to constrain the neutrino-unparticle couplings for differe...
متن کاملUnparticle physics.
I discuss some simple aspects of the low-energy physics of a nontrivial scale invariant sector of an effective field theory-physics that cannot be described in terms of particles. I argue that it is important to take seriously the possibility that the unparticle stuff described by such a theory might actually exist in our world. I suggest a scenario in which some details of the production of un...
متن کاملCoherent elastic neutrino-nucleus scattering
I describe physics potential and experimental prospects for coherent elastic neutrino-nucleus scattering (CEvNS), a process which has not yet been observed. Germaniumbased detectors represent a promising technology for CEvNS experiments. I focus primarily on stopped-pion neutrino sources. 1. Coherent elastic neutrino-nucleus scattering Coherent elastic neutrino-nucleus scattering (“CEvNS”1) is ...
متن کاملNeutrino Cross Sections and Scattering Physics
Large flux uncertainties and small cross sections have made neutrino scattering physics a challenge. However, a worthwhile challenge, as these tiny particle interactions can teach us a lot about neutrinos themselves, the weak interaction, and nucleon structure. As well, knowledge of these cross sections is crucial input to the growing field of neutrino oscillation physics. New, intense, well un...
متن کاملA Note on Unparticle Decays
The coupling of an unparticle operator OU to Standard Model particles opens up the possibility of unparticle decays into standard model fields. We study this issue by analyzing the pole structure (and spectral function) of the unparticle propagator, corrected to account for one-loop polarization effects from virtual SM particles. We find that the propagator of a scalar unparticle (of scaling di...
