[SLAC] [SLAC Pubs and Reports] SLAC-PUB-7792Light Active and Sterile Neutrinos from Compositeness Abstract Neutrinos can have naturally small Dirac masses if the Standard Model singlet right-handed neutrinos are light composite fermions. Theories which produce light composite fermions typically generate many of them, three of which can marry the left-handed neutrinos with small Dirac masses. The rest can serve as sterile states which can mix with the Standard Model neutrinos. We present explicit models illustrating this idea. %We present explicit models that produce light active and %sterile neutrinos and show how realistic masses %and active--sterile mixing angles can arise. (Equations render on Windows, Mac OS, AIX, Linux, Solaris, and IRIX with the techexplorer plug-in.)
