Abstract
The OPERA experiment was designed to discover the ντ appearance in a pure νμ beam, resulting from neutrino oscillations. The detector, located in the underground Gran Sasso Laboratory, consisted of an emulsion/lead target complemented by electronic detectors and was exposed, from 2008 to 2012, to the (CERN Neutrinos to Gran Sasso (CNGS)) beam, an almost pure νμ beam with a baseline of 730 km, collecting a total of 1.8 1020 protons on target. OPERA was unique in its capability of detecting all three neutrino flavors. OPERA discovered νμ → ντ oscillations in appearance mode with a significance of 6.1σ. In this review, we report the major achievements of the OPERA experiment and its legacy in the nuclear emulsion technology.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
