Description
A joint oscillation analysis of atmospheric neutrinos at Super-Kamiokande
(SK) and accelerator neutrinos at Tokai-to-Kamioka (T2K) is in preparation.
SK atmospheric neutrinos have sensitivity to neutrino mass ordering via matter
effects in the Earth, whereas accelerator neutrinos have stronger sensitivity to
the CP violation phase thanks to selective beam operation and low $\nu_e$ back-
ground. A joint fit is expected to provide mutual benefits via the resolution of
degeneracies between these parameters and systematic parameter constraints.
Here we present studies of the expected sensitivity to oscillation parameters,
demonstrating the complementarity of oscillation parameter constraints from
each experiment, and analyze the impact of T2K near detector constraints on
the SK atmospheric fit. [Details of the systematics model and calculation meth-
ods are presented in two separate posters.]
