Description
We investigate the sources of neutrino mass generation in Little Higgs theories, by
confining ourselves to the Littlest Higgs scenario. Our conclusion is that the most
satisfactory way of incorporating neutrino masses is to include a lepton-number
violating interaction between the scalar triplet and lepton doublets. The
tree-level neutrino masses are generated by the vacuum expectation value of the
triplet. We also
calculate the various decay branching ratios of the charged and neutral scalar
triplet states, in regions of the parameter space consistent with the observed
neutrino masses, hoping to search for signals of lepton-number violating interactions
in collider experiments.
