Özet

A first result of the search for νμ → νe oscillations in the OPERA experiment, located at the Gran Sasso Underground Laboratory, is presented. The experiment looked for the appearance of νe in the CNGS neutrino beam using the data collected in 2008 and 2009. Data are compatible with the non-oscillation hypothesis in the three-flavour mixing model. A further analysis of the same data constrains the non-standard oscillation parameters θnew and Δm new2 suggested by the LSND and MiniBooNE experiments. For large Δ Δmnew2 values (>0.1 eV 2), the OPERA 90% C.L. upper limit on sin2(2θ new) based on a Bayesian statistical method reaches the value 7.2 × 10-3. © 2013 SISSA.
