We report the final measurement of the neutrino oscillation parameters Δm^2_32 and sin 2θ_23 using all data from the MINOS and MINOS+ experiments. These data were collected using a total exposure of 23.76×10^20 protons on target producing νμ and anti νμ beams and 60.75 kt yr exposure to atmospheric neutrinos. The measurement of the disappearance of νμ and the appearance of νe events between the Near and Far detectors yields |Δm^2_32| = 2.40 +0.08 −0.09 (2.45 +0.07 −0.08) ×10^−3 eV^2 and sin 2θ_23 = 0.43 +0.20 −0.04 (0.42 +0.07 −0.03) at 68% C.L. for normal (inverted) hierarchy.

Abstract

We report the final measurement of the neutrino oscillation parameters Δm^2_32 and sin 2θ_23 using all data from the MINOS and MINOS+ experiments. These data were collected using a total exposure of 23.76×10^20 protons on target producing νμ and anti νμ beams and 60.75 kt yr exposure to atmospheric neutrinos. The measurement of the disappearance of νμ and the appearance of νe events between the Near and Far detectors yields |Δm^2_32| = 2.40 +0.08 −0.09 (2.45 +0.07 −0.08) ×10^−3 eV^2 and sin 2θ_23 = 0.43 +0.20 −0.04 (0.42 +0.07 −0.03) at 68% C.L. for normal (inverted) hierarchy.
