Well, the verdict is in: MiniBOONE fails to confirm the e-flavor neutrino appearance once claimed on the basis of the LSND experiment. There now is NO evidence of appearance of a new neutrino flavor as a function of anything, including distance of neutrino propagation. Hopefully, this will revitalize efforts to come up with a new and better theory. The current oscillation theory is based on a group theory of multiple neutrino mass eigenstates and implies violation of conservation of energy or momentum, or both, in a freely propagating particle. Physicists have been willing to trade off these conservation laws for too long. All we know now, from K2K and similar experiments, is that neutrinos of a certain flavor at the creation point are detected with less probability at long distances than at short. This is called a "disappearance" phenomenon and is well supported by the evidence. It can't be mass eigenstate oscillation, if we want our precious energy and momentum laws. These laws work well in all the rest of physics, including particle interactions. Why drop them just to fiddle with some group math? Is flavor a (proper) time dependent property? Is it distance dependent? Can an interaction cross-section depend on proper time or distance? Does flavor decay? Do neutrinos decay? Does anyone have a good idea which is consistent with known physical laws?
