Resumo
We report the final measurement of the neutrino oscillation parameters Δm2
32 and sin2 θ23 using all
data from the MINOS and MINOSþ experiments. These data were collected using a total exposure of
23.76 × 1020 protons on target producing νμ and ¯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 jΔm2
32j ¼ 2.40þ0.08 −0.09 ð2.45þ0.07 −0.08 Þ × 10−3 eV2 and sin2 θ23 ¼ 0.43þ0.20 −0.04 ð0.42þ0.07 −0.03 Þ at
68% C.L. for normal (inverted) hierarchy.
