Atmospheric neutrino oscillation analysis with subleading effects in Super-Kamiokande I, II, and III

We present a search for nonzero {theta}{sub 13} and deviations of sin{sup 2{theta}}{sub 23} from 0.5 in the oscillations of atmospheric neutrino data from Super-Kamiokande I, II, and III. No distortions of the neutrino flux consistent with nonzero {theta}{sub 13} are found and both neutrino mass hierarchy hypotheses are in agreement with the data. The data are best fit at {Delta}m{sup 2}=2.1x10{sup -3} eV{sup 2}, sin{sup 2{theta}}{sub 13}=0.0, and sin{sup 2{theta}}{sub 23}=0.5. In the normal (inverted) hierarchy {theta}{sub 13} and {Delta}m{sup 2} are constrained at the one-dimensional 90% C.L. to sin{sup 2{theta}}{sub 13}<0.04(0.09) and 1.9(1.7)x10{sup -3}<{Delta}m{sup 2}<2.6(2.7)x10{sup -3} eV{sup 2}. The atmospheric mixing angle is within 0.407{<=}sin{sup 2{theta}}{sub 23{<=}}0.583 at 90% C.L.
