A new method of measurement of the velocities of solar neutrinos

Abstract

A new method of measurement of the velocities of solar electron antineutrinos is proposed. The method is based on the assumption, that if the neutrino detector having a shape of a pipe and providing a proper angular resolution, is directed onto the optical "image" of the sun, then it would detect solar neutrinos with velocities $V_{\widetildeν_{e}}$ $=c$. Here c is the velocity of light. It is expected that the less is the value of $V_{\widetilde ν_{e}}$, the larger would be the angular lagging of the "image" of these neutrinos relative to the position of the optical "image" of the sun. Therefore, one can detect solar neutrinos with different energies by changing the angle between the axis of a detector pipe and the direction to the "image" of the sun. Also, the method gives unique possibility to check hypotheses predicting an existence of solar neutrinos with $V_{\widetildeν_{e}}>c$. In this case the "image" of such solar neutrinos on the sky should pass the "image" of the sun.
