Parametric resonance in neutrino oscillations in matter ∗
Neutrino oscillations in matter can exhibit a specific resonance enhancement – parametric resonance, which is different from the MSW resonance. Oscillations of atmospheric and solar neutrinos inside the earth can undergo parametric enhancement when neutrino trajectories cross the core of the earth. In this paper we review the parametric resonance of neutrino oscillations in matter. In particula...
متن کاملParametric Resonance in Oscillations of Atmospheric Neutrinos?
We consider a solution of the atmospheric neutrino problem based on oscillations of muon neutrinos to sterile neutrinos: νμ ↔ νs. The zenith angle (Θ) dependences of the neutrino and upward-going muon fluxes in presence of these oscillations are studied. The dependences have characteristic form with two dips: at cosΘ = −0.6÷−0.2 and cosΘ = −1.0÷−0.8. The latter dip is due to parametric resonanc...
متن کاملResonance in Forced Oscillations of an Accretion Disk and Kilohertz Quasi–Periodic Oscillations
We have performed numerical simulations of a radially perturbed “accretion” torus around a black hole or neutron star and find that the torus performs radial and vertical motions at the appropriate epicyclic frequencies. We find clear evidence that vertical motions are excited in a nonlinear resonance when the applied perturbation is periodic in time. The strongest resonant response occurs when...
متن کاملRemarks on parametric resonance of neutrino oscillations in the earth
Neutrino oscillations in matter can exhibit a specific resonance enhancement – parametric resonance, which is different from the MSW resonance. Recently it has been shown that the oscillations of atmospheric and solar neutrinos inside the earth can undergo parametric enhancement when neutrino trajectories cross the core of the earth. In this paper we continue the study of the parametric resonan...
متن کاملFourier Analysis of the Parametric Resonance in Neutrino Oscillations
Parametric enhancement of the appearance probability of the neutrino oscillation under the inhomogeneous matter is studied. Fourier expansion of the matter density profile leads to a simple resonance condition and manifests that each Fourier mode modifies the energy spectrum of oscillation probability at around the corresponding energy; below the MSW resonance energy, a large-scale variation mo...
