If an appearance signal is observed, it will imply Physics Beyond the Standard Model such as the existence of light sterile neutrino.6 pages, 4 figures. Plenary talk at the Neutrino Oscillation Workshop (NOW2006), September 2006, to be published in Nucl.Phys. B (Proc. Suppl.)High Energy Physics - Experimenttext
