  • Astrophysical limits on gauge invariance breaking in electrodynamics with torsion 
    Sivaram, C; de Andrade, L. C. G (Kluwer Academic Publishers, 1993-02)
    General relativistic electrodynamics in a torsion background can give rise to a situation where the photons can have a non-zero rest mass and magnetic moment. Astrophysical limits are used to constrain these parameters.
  • Astrophysical Limits on the Neutrino Electric Charge 
    Sivaram, C (Japan Science and Technology Agency, 1989-09)
    It was recentrly shown that the bunching in time of the neutrinos detected from SN1987A in LMC implies among other things that the neutrino electric charge q is 10/sup(-17) times as small as the electron charge. We point ...
