Large mixing angle oscillations as a probe of the deep solar interior
نویسنده
چکیده
We re-examine the sensitivity of solar neutrino oscillations to noise in the solar interior using the best current estimates of neutrino properties. Our results show that the measurement of neutrino properties at KamLAND provides new information about fluctuations in the solar environment on scales to which standard helioseismic constraints are largely insensitive. We also show how the determination of neutrino oscillation parameters from a combined fit of KamLAND and solar data depends strongly on the magnitude of solar density fluctuations. We argue that a resonance between helioseismic and Alfvén waves might provide a physical mechanism for generating these fluctuations and, if so, neutrino-oscillation measurements could be used to constrain the size of magnetic fields deep within the solar radiative zone. Subject headings: elementary particles (neutrino) – magnetohydrodynamics – sun: interior – sun: oscillations – sun: magnetic fields

There are reasons to believe that mechanisms exist in the solar interior which lead to random density perturbations in the resonant region of the Large Mixing Angle solution to the solar neutrino problem. We find that, in the presence of these density perturbations, the best fit point in the (sin 2θ,∆m) parameter space moves to smaller values, compared with the values obtained for the standard ...

متن کاملStandard and non-standard neutrino properties
I review the interpretation of solar and atmospheric neutrino data in terms neutrino oscillations and describe some ways to account for the required neutrino masses and mixing angles from first principles, both within topdown and bottom-up approaches. I also discuss non-oscillation phenomena such as ββ0ν which may probe the absolute scale of neutrino mass, and also reveal its Majorana nature. I...
متن کاملHow well do we (and will we) know solar neutrino fluxes and oscillation parameters?
Individual neutrino fluxes are not well determined by the four operating solar neutrino experiments. Assuming neutrino oscillations occur, the pp electron neutrino flux is uncertain by a factor of 2, the B flux by a factor of 5, and the Be flux by a factor of 45. For matter-enhanced oscillation ~MSW! solutions, the range of allowed differences of squared neutrino masses, Dm, varies between 4310...
