Description
This poster presents the latest atmospheric neutrino results from the
MINOS experiment. The results are based on a data set of 1657 live-days,
and combine together observations of contained vertex neutrino interactions
and neutrino-induced upward muons in the MINOS far detector. The measured
curvature of muons in the MINOS magnetic field is used to separate neutrinos
and anti-neutrinos, and the observed ratio of neutrinos to anti-neutrinos
is compared to the Monte Carlo expectation. The data are separated into
bins of L/E resolution, and a maximum likelihood fit to the observed L/E
distributions is used to determine the oscillation parameters separately
for neutrinos and anti-neutrinos. Confidence limits are placed on the
difference between these oscillation parameters.
