Why the flavor conflict?[edit]

The article should explain how the results conflict with the expectatipn of 3 neutrimo flavors. ᛭ LokiClock (talk) 07:07, 25 December 2010 (UTC)

Yeah, I don't get it. What were the conflicts, exactly? linas (talk) 19:34, 18 August 2012 (UTC)
There are/were a couple levels of conflict. First, at the time of the initial results, there was a claim that the measurement itself might be faulty, and another experiment looking at (almost) the same parameter space which disagreed with the findings. I was the author on a paper published simultaneously with the original oscillation claim which disputed its conclusion from within the collaboration (which is why I should not edit the content of this page myself). The follow-up analyses done through the years have gone back and forth a bit on the real significance of the result, and in fact while in the analysis framework of the original publication the newer experiment Mini-BoooNE "rules out" the original result, analyses with more degrees of freedom allow some region. Sterile neutrino solutions are prominent ones with significant allowed parameter space, especially given the constraints of what is known from other experiments in different channels. If someone is interested I can point to some sources and do my best to be neutral, but that person should look critically at whatever I say (even though I am right ;) )JimHill (talk) 02:54, 6 December 2013 (UTC)

Sterile neutrino hypothesis excluded?[edit]

The sentence: "Cosmological data bound the mass of the sterile neutrino to ms < 0.26eV (0.44eV) at 95% (99.9%) confidence limit, excluding at high significance the sterile neutrino hypothesis as an explanation of the LSND anomaly" is a bit too strong. It is the conclusion of the referenced paper, but many other papers come to different conclusions. It depends on how much you restrict your model space (do we have dark energy evolving, are the ordinary neutrinos assumed massive), the assumptions you make about the sterile neutrino (like no lepton asymmetry, no late time reheating phase) and how many datasets you combine. The more realistic bound from cosmology is probably around ms < 2eV. Unsigned comment added 06:28, 23 May 2012‎ User talk: .
