BEYOND THE STANDARD MODEL - WORKING GROUP-REPORT

This report summarises the activities of the working group on 'Physics beyond the Standard Model'. The results of investigations in incorpor ating R-parity in grand unification, the possibility of a light charge d Higgs boson in extension of MSSM and radiative generation of neutral vector boson self-couplings within the MSSM are described. Also given is an account of activities in neutrino physics, namely a proposal fo r a study of the atmospheric muon anomaly in deep underground mines, a field theoretic study of neutrino oscillations and a mechanism to gen erate appropriate masses of three active plus one sterile neutrino spe cies.
