Title: Combined Analysis of νμ Disappearance and νμνe Appearance in MINOS Using Accelerator and Atmospheric Neutrinos

We report on a new analysis of neutrino oscillations in MINOS using the complete set of accelerator and atmospheric data. The analysis combines the $$\nu_{\mu}$$ disappearance and $$\nu_{e}$$ appearance data using the three-flavor formalism. We measure $$|\Delta m^{2}_{32}|=[2.28-2.46]\times10^{-3}\mbox{\,eV}^{2}$$ (68% C.L.) and $$\sin^{2}\theta_{23}=0.35-0.65$$ (90% C.L.) in the normal hierarchy, and $$|\Delta m^{2}_{32}|=[2.32-2.53]\times10^{-3}\mbox{\,eV}^{2}$$ (68% C.L.) and $$\sin^{2}\theta_{23}=0.34-0.67$$ (90% C.L.) in the inverted hierarchy. The data also constrain $$\delta_{CP}$$, the $$\theta_{23}$$ octant degeneracy and the mass hierarchy; we disfavor 36% (11%) of this three-parameter space at 68% (90%) C.L.
