Unknowns after the SNO charged-current measurement.

چکیده
We perform a model-independent analysis of solar neutrino flux rates including the recent charged-current measurement at the Sudbury Neutrino Observatory (SNO). We derive a universal sum rule involving SNO and SuperKamiokande rates, and show that the SNO neutral-current measurement cannot fix the fraction of solar nu(e) oscillating to sterile neutrinos. The large uncertainty in the standard solar model (8)B flux impedes a determination of the sterile neutrino fraction.

Four–neutrino Oscillations at SNO
We discuss the potential of the Sudbury Neutrino Observatory (SNO) to constraint the four–neutrino mixing schemes favoured by the results of all neutrino oscillations experiments. These schemes allow simultaneous transitions of solar ν ′ es into active νμ’s, ντ ’s and sterile νs controlled by the additional parameter cos(θ23) cos(θ24) and they contain as limiting cases the pure νe–active and νe...
متن کاملA Few Comments after the Charged Current Measurement at the Sudbury Neutrino Observatory
The comparison of the SNO charged current result with the solar neutrino signal measured by Super-Kamiokande has provided, for the first time, the evidence of a non electron flavour active neutrino component in the solar flux. We remark here that this evidence can be obtained in a model independent way, i.e. without any assumpion about solar models, about the energy dependence of the neutrino o...

متن کاملTests of electron flavor conservation with the Sudbury Neutrino Observatory.
We analyze tests of electron flavor conservation that can be performed at the Sudbury Neutrino Observatory ~SNO!. These tests, which utilize B solar neutrinos interacting with deuterium, measure ~1! the shape of the recoil electron spectrum in charged-current ~CC! interactions ~the CC spectrum shape!, and ~2! the ratio of the number of charged-current to neutral current ~NC! events ~the CC/NC r...
متن کاملSolar neutrinos: global analysis and implications for SNO
We present a global analysis of all the available solar neutrino data treating consistently the B and hep neutrino fluxes as free parameters. The analysis reveals at 99.7% C.L. eight currently-allowed discrete regions in two-neutrino oscillation space, five regions corresponding to active neutrinos and three corresponding to sterile neutrinos. Most of the allowed oscillation solutions are robus...
