MINOS (Main Injector Neutrino Oscillation Search) experiment has been designed
to search for a change in the
avor composition of a beam of muon neutrinos
as they travel between the Near Detector at Fermi National Accelerator Laboratory
and the Far Detector in the Soudan mine in Minnesota, 735 km from the target.
The MINOS oscillation analysis is mainly performed with the charged current
(CC) events and sensitive to constrain high-delta m2 values. However, the quasi-elastic
(QEL) charged current interaction is dominant in the energy region important to
access low-delta m2 values. For further improvement, the QEL oscillation analysis is performed
in this dissertation. A data sample based on a total of 2.50 x 1020 POT
is used for this analysis. In summary, 55 QEL-like events are observed at the
Far detector while 87.06 +/- 13.17 (syst:) events are expected with null oscillation
hypothesis. These data are consistent with vm disappearance via oscillation with
delta m2 = 2.10 +/- 0.37 (stat:) +/- 0.24 (syst:) eV2 and the maximal mixing angle.
