The observation of electron neutrino-like events allows MINOS scientists to extract information about a quantity called sin2 2θ13. If muon neutrinos don't transform into electron neutrinos, sin2 2θ13 is zero. The new MINOS result constrains this quantity to a range between 0 and 0.12, improving on results it obtained with smaller data sets in 2009 and 2010. The MINOS range is consistent with the T2K range for sin2 2θ13, which is between 0.03 and 0.28. According to the T2K data, the most likely value is 0.11. The MINOS result prefers a value of 0.04, and its data indicates that sin2 2θ13 is non-zero at the 89% confidence level.
