  Abstract We report measurements by the T2K experiment of the parameters theta(23) and Delta m(32)(2) governing the disappearance of muon neutrinos and antineutrinos in the three-flavor neutrino oscillation model. Utilizing the ability of the experiment to run with either a mainly neutrino or a mainly antineutrino beam, the parameters are measured separately for neutrinos and antineutrinos. Using 7.482 x 10(20) POT in neutrino running mode and 7.471 x 10(20) POT in antineutrino mode, T2K obtained sin(2) (theta(23)) = 0.51(-0.07)(+0.08) and Delta (m) over bar (2)(32) = (+0.15)(-2.53) -0.13 x 10(-3) eV(2)/c(4) for neutrinos, and sin(2) ((theta) over bar (23)) = 0.42(-0.07)(+0.25) and Delta(m) over bar (2)(32) = 2.55(-0.27)(+0.33) x 10(-3) eV(2)/c(4) for antineutrinos (assuming normal mass ordering). No significant differences between the values of the parameters describing the disappearance of muon neutrinos and antineutrinos were observed.
