First NOvA-T2K joint result published in Nature

This result is the first neutrino oscillation measurement that uses data from two long-baseline experiments simultaneously. Members of the Tufts neutrino group work on NOvA, and NOvA joined forces with the T2K experiment to produce this measurement. It’s the culmination of 6 years of hard work to understand how best to combine the individual experiments’ data.

Posterior probabilities—the likelihood of any particular value or combination of values being the correct one—for the parameters in the neutrino oscillation formalism that is measured by NOvA & T2K. The most likely combination (according to this analysis) is one that favors strong CP violation and the inverted mass ordering. More in the paper!

Studies that showed that the two datasets could be treated as largely independent originated with work in the Tufts group. Prof. Wolcott also is currently one of the scientific liaisons between the two experiments.

Tufts Now also ran a very nice article about the results:
