EFFECT OF MAGNETIC-FIELD-INDUCED TORSION ON NEUTRINOS AND SUPERNOVA COLLAPSE

The neutrino emission from supernova 1987A is being studied by taking into consideration the effect of the magnetic field present in the sta r. The magnetic field generates an anisotropic feature in the local sp ace-time, which in turn leads to the cancellation of the axial-vector part of the neutrino current. The interaction cross-section of these n eutrinos in the course of their interaction with matter on Earth has a n inverse square energy dependence. The present work presents the calc ulations based on this changed cross-section that relates to predictio ns of the expected number of events at KAMIOKANDE on the basis of the Mont Blanc signal. It might be interesting to take a look into the imp lications of these results.
