The Charged Neutrino: A New Approach to the Solar Neutrino Problem
We have considered the effect of the reduction of the solar neutrino flux on
earth due to the deflection of the charged neutrino by the magnetic field of
the solar convective zone. The antisymmetry of this magnetic field about the
plane of the solar equator induces the anisotropy of the solar neutrino flux
thus creating the deficit of the neutrino flux on the earth. The deficit has
been estimated in terms of solar and neutrino parameters and the condition of a
50 \% deficit has been obtained: Q_{\nu} gradH \agt 10^{-18} eG/cm where
is the neutrino electric charge, is the gradient of the solar
toroidal magnetic field, e is the electron charge. Some attractive experimental
consequences of this scenario are qualitatively discussed.Comment: 15 pages, UM-P/94-26, in REVTE
Maverick Examples Of Coset Conformal Field Theories
We present coset conformal field theories whose spectrum is not determined by
the identification current method. In these ``maverick'' cosets there is a
larger symmetry identifying primary fields than under the identification
current. We find an A-D-E classification of these mavericks. }Comment: 16pages , reportSWAT-93-0
Magnetic Monopole and the Finite Photon Mass: Are They Compatible?
We analyze the role played by the gauge invariance for the existence of Dirac
monopole. To this end, we consider the electrodynamics with massive photon and
ask if the magnetic charge can be introduced there. We show that the derivation
of the Dirac quantization condition based on the angular momentum algebra
cannot be generalized to the case of massive electrodynamics. Possible
implications of this result are briefly discussed.Comment: 12 pages, revtex, no figure
