Περίληψη:
We report an improved measurement of (nu) over bar (mu) disappearance
over a distance of 735 km using the MINOS detectors and the Fermilab
Main Injector neutrino beam in a (nu) over bar (mu)-enhanced
configuration. From a total exposure of 2.95 x 10(20) protons on target,
of which 42% have not been previously analyzed, we make the most
precise measurement of Delta(m) over bar (2) =
[2.62(-0.28)(+0.31)(stat) +/- 0.09(syst)] x 10(-3) eV(2) and constrain
the (nu) over bar (mu) mixing angle sin(2)(2 (theta) over bar) > 0.75
(90% C.L.). These values are in agreement with Delta m(2) and sin(2)(2
theta) measured for nu(mu), removing the tension reported in [P.
Adamson et al. (MINOS), Phys. Rev. Lett. 107, 021801 (2011).].
