Search for the Invisibly Decaying Higgs Particle at LEP and the LHC
The Higgs particle can have dominantly invisible decay in a large class of
Majoron models as well as some SUSY models. The LEP signal and mass limit for a
Higgs particle undergoing invisible decay are explored. They are found to be
very similar to those for the standard model decay. The best signatures and
discovery limit for an invisibly decaying Higgs particle at the LHC are also
discussed.

Solar Neutrino Oscillation - An Overview
After a brief summary of the neutrino oscillation formalism and the solar
neutrino sources and experiments I discuss the matter effect on solar neutrino
oscillation. Then I discuss how the resulting alternative solutions are
experimentally resolved in favour of the LMA solution, with particular exphasis
on the SK, SNO and KL data.Comment: 13 pages Latex plus 10 eps figures, Plenary Talk at the Xth
