Overview

Results are reported from an improved measurement of \\(\\nu_\\mu \\rightarrow \\nu_e\\) transitions by the NOvA experiment. Using an exposure equivalent to \\(6.05\\times10^{20}\\) protons-on-target 33 \\(\\nu_e\\) candidates were observed with a background of \\(8.2\\pm0.8\\) (syst.). Combined with the latest NOvA \\(\\nu_\\mu\\) disappearance data and external constraints from reactor experiments on \\(\\sin^22\\theta_{13}\\), the hypothesis of inverted mass hierarchy with \\(\\theta_{23}\\) in the lower octant is disfavored at greater than \\(93\\%\\) C.L. for all values of \\(\\delta_{CP}\\).
