Abstract

The OPERA long-baseline neutrino-oscillation experiment has observed the direct appearance of ν_τ in the CNGS ν_μ beam. Two large muon magnetic spectrometers are used to identify muons produced in the τ leptonic decay and in ν_μ CC interactions by measuring their charge and momentum. Besides the kinematic analysis of the τ decays, background resulting from the decay of charmed particles produced in ν_μ CC interactions is reduced by efficiently identifying the muon track. A new method for the charge sign determination has been applied, via a weighted angular matching of the straight track-segments reconstructed in the different parts of the dipole magnets. Results obtained for Monte Carlo and real data are presented. Comparison with a method where no matching is used shows a significant reduction of up to 40% of the fraction of wrongly determined charges.
