Neutrino v. Anti-Neutrino Discrepencies?

PregnancyFermilab investigators employed on the MINOS experiment hit institute a 40% disagreement between neutrino and anti-neutrino oscillations, with a two accepted deflexion significance, in a termination declared yesterday (in a press release).There are reasons for skepticism. A disagreement would seem to show that neutrinos and anti-neutrinos of the same savor hit assorted masses. Yet, every another famous particle has precisely the same coefficient as its anti-particle. In short, it is belike a fluke. While a 5% quantity of a statistical platyhelminth wouldn't bother a ethnic scientist, physicists wait most quaternary accepted deviations of certainty, specially when a termination is at ratio with empirically substantially established preceding theory.But, since every anomalous termination starts out existence statistically insignificant, it is worth noting. If true, it module be one of those "who sequential that?" moments in the story of science. Most plausibly it would refer some sort of CP violation. This would earmark for a scenario in which neutrinos and anti-neutrinos hit the same mass, but their undulation frequencies are not the same because anti-matter would be disfavored qualifying to matter in some way.Copyright saint Oh-Willeke (2009)Pregnancy helper
