First oscillation results from the NOvA experiment

The NuMI Off-axis νe Appearance (NOvA) experiment is a two-detector, long-baseline neutrino oscillation experiment which addresses some of the main open questions in the neutrino sector through precision measurements of neutrino and antineutrino oscillations. NOvA uses the  upgraded NuMI neutrino beam at the Fermi National Accelerator Laboratory and a highly active, finely segmented 14-kton far detector at Ash River, Minnesota. This so-called “fully-active” design provides an outstanding event identification capacity, which allows for precision measurements of the oscillation parameters in both the appearance and disappearance of neutrinos and antineutrinos. In particular, NOvA will provide constraints on θ13, θ23, |Δm2atm|, the neutrino mass ordering and the CP-violation phase. The NOvA collaboration recently released its first oscillation physics results using 8% of the nominal exposure. I will report on NOvA’s first neutrino oscillation analyses and results.
