Abstract
We report measurements by the T2K experiment of the parameters $\theta_{23}$
and $\Delta m^2_{32}$ which govern the disappearance of muon neutrinos and
antineutrinos in the three-flavor PMNS neutrino oscillation model at T2K's
neutrino energy and propagation distance. Utilizing the ability of the
experiment to run with either a mainly neutrino or a mainly antineutrino beam,
muon-like events from each beam mode are used to measure these parameters
separately for neutrino and antineutrino oscillations. Data taken from $1.49
\times 10^{21}$ protons on target (POT) in neutrino mode and $1.64 \times
10^{21}$ POT in antineutrino mode are used. The best-fit values obtained by T2K
were $\sin^2\left(\theta_{23}\right)=0.51^{+0.06}_{-0.07}
\left(0.43^{+0.21}_{-0.05}\right)$ and $\Delta m^2_{32}=2.47^{+0.08}_{-0.09}
\left(2.50^{+0.18}_{-0.13}\right)$\evmass for neutrinos (antineutrinos). No
significant differences between the values of the parameters describing the
disappearance of muon neutrinos and antineutrinos were observed. An analysis
using an effective two-flavor neutrino oscillation model where the sine of the
mixing angle is allowed to take non-physical values larger than 1 is also
performed to check the consistency of our data with the three-flavor model. Our
data were found to be consistent with a physical value for the mixing angle.
