Low Scale Theories: Light Neutrinos and Unification of Gauge Couplings

Abstract

Mechanism for generation of suppressed neutrino masses, within low scale theories, is considered. The mechanism do not have extradimensional nature and is realized through extended $SU(2{)}_L$ scalar multiplets. Latters, in some cases, are also crucial for successful low scale unification.
