Query: Twisted Flavors and Tri/bi-Maximal Neutrino Mixing   A new framework for handling flavor symmetry breaking in the neutrino sector
is discussed where the source of symmetry breaking is traced to the global
property of right-handed neutrinos in extra-dimensional space. Light neutrino
phenomenology has rich and robust predictions such as the tri/bi-maximal form
of generation mixing, controlled mass spectrum, and no need of flavor mixing
couplings in the theory.
