アブストラクト: There is compelling evidence for the existence of small neutrino masses and large mixing from the Solar, Atmospheric, Accelerator as well as from the WMAP data. We will discuss the neutrino mass generation in the Standard Model and beyond. We will concentrate on the Little Higgs (LH) model which provides an attractive frame work for the generation of neutrino masses and lepton number (LN) and flavour violating (LF) interactions. We will discuss the bounds on neutrino majorana mass and exotic lepton number violating couplings from processes like neutrinoless double beta decay, muon positron conversion and LNV K and Tau decays. We will then go on to discuss the LH model with T parity which has the interesting feature of providing a candidate for the dark matter (WIMP) in the presence of T parity conservation. Anomalous magnetic moment of muons, radiative and semileptonic LFV decay of leptons will be discussed.
