What do we (not) know theoretically about solar neutrino fluxes?

ar X iv : a st ro - p h / 04 02 11 4 v 2 26 M ar 2 00 4 What do we ( not ) know theoretically about solar neutrino fluxes ?

Solar model predictions of B and p-p neutrinos agree with the experimentally-determined fluxes (including oscillations): φ(pp)measured = (1.02±0.02±0.01)φ(pp)theory, and φ( B)measured = (0.88± 0.04±0.23)φ(B)theory, 1σ experimental and theoretical uncertainties, respectively. We use improved input data for nuclear fusion reactions, the equation of state, and the chemical composition of the Sun. ...

What Do Solar Models Tell Us about Solar Neutrino Experiments?

If the published event rates of the chlorine and Kamiokande solar neutrino experiments are correct, then the energy spectrum of neutrinos produced by the decay of B in the sun must be different from the energy spectrum determined from laboratory nuclear physics measurements. This change in the energy spectrum requires physics beyond the standard electroweak model. In addition, the GALLEX and SA...

Solar Models with Helioseismic Constraints and the Solar Neutrino Problem

Imposing a constraint of the sound-speed profile determined from helioseismology and updating the microphysics, we have revised our seismic solar model, constructed with the assumption of a homogeneous metal abundance distribution, and have shown that the theoretically expected neutrino fluxes are still significantly more than the observations. With the same sound-speed profile constraint, we a...

Diagnostic and therapeutic challenges for dermatologists: What shall we do when we don’t know what to do?

What shall we do when we have done everything we could for the diagnosis and treatment of a patient, but were not successful? What shall we do when there is no definite treatment for a patient? What shall we do when we have no diagnosis or treatment for a patient? Some useful suggestions are presented here to get rid of these situations.
