A possible solution to the solar neutrino problem is to posit a massive, stable, neutral particle as part of the Sun's primordial composition. If that particle has a mass between 5 and 60 GeV, then it will populate only the inner ''solar neutrino unit-producing'' core and not the larger luminosity-producing region. If it has a scattering cross section on protons of 4 x 10/sup -36/ cm/sup 2/, then a fractional abundance of 10/sup -12/ will have order-unity effect on the Sun's thermal transport, in the direction of decreasing the expected neutrino signature. For smaller cross sections, the required abundance rises in inverse proportion, so that cross sections as small as 10/sup -46/ cm/sup 2/ are effective if the concentration is as large as approx.10/sup -2/. The photino is a possible candidate particle; mirror neutrinos may also be candidates.
