Solar Neutrinos Before and After KamLAND
We use the recently reported KamLANDmeasurements on oscillations of reactor anti-neutrinos, together with the data of previously reported solar neutrino experiments, to show that: (1) the total B neutrino flux emitted by the Sun is 1.00(1± 0.06) of the standard solar model (BP00) predicted flux, (2) the fraction of the B flux that is in the form of sterile neutrinos is 0.00 −0.00, (3) the KamLA...
متن کاملSolar neutrinos before and after Neutrino 2004
We compare, using a three neutrino analysis, the allowed neutrino oscillation parameters and solar neutrino fluxes determined by the experimental data available Before and After Neutrino 2004. New data available after Neutrino 2004 include refined KamLAND and gallium measurements. We use six different approaches to analyzing the KamLAND data. We present detailed results using all the available ...
متن کاملSearches for sterile component with solar neutrinos and KamLAND
Possible mixing of the active and sterile neutrinos has been considered both in the single ∆m approximation and in the case of more than one ∆m. We perform global fit of the available solar neutrino data with free boron neutrino flux in the single ∆m context. The best fit value corresponds to zero fraction of sterile component η = 0. We get the upper bounds: η < 0.26(0.64) at 1σ (3σ). Due to de...
متن کاملNeutrino Properties Before and After KamLAND
We review neutrino oscillation physics, including the determination of mass splittings and mixings from current solar, atmospheric, reactor and accelerator neutrino data. A brief discussion is given of cosmological and astrophysical implications. Non-oscillation phenomena such as neutrinoless double beta decay would, if discovered, probe the absolute scale of neutrino mass and also reveal their...
متن کاملSolar Neutrino oscillation parameters after KamLAND
We explore the impact of the data from the KamLAND experiment in constraining neutrino mass and mixing angles involved in solar neutrino oscillations. In particular we discuss the precision with which we can determine the the mass squared difference ∆m2⊙ and the mixing angle θ⊙ from combined solar and KamLAND data. We show that the precision with which ∆m2⊙ can be determined improves drasticall...
