Title: First measurement of muon-neutrino disappearance in NOvA

This paper reports the first measurement using the NOvA detectors of $$\nu_\mu$$ disappearance in a $$\nu_\mu$$ beam. The analysis uses a 14 kton-equivalent exposure of $$2.74 \times 10^{20}$$ protons-on-target from the Fermilab NuMI beam. Assuming the normal neutrino mass hierarchy, we measure $$\Delta m^{2}_{32}=(2.52^{+0.20}_{-0.18})\times 10^{-3}$$ eV$$^{2}$$ and $$\sin^2\theta_{23}$$ in the range 0.38-0.65, both at the 68% confidence level, with two statistically-degenerate best fit points at $$\sin^2\theta_{23} = $$ 0.43 and 0.60. Results for the inverted mass hierarchy are also presented.
