OPERA is a long-baseline experiment designed to search for νμ→ντνμ→ντ oscillations in appearance mode. It was based at the INFN Gran Sasso laboratory (LNGS) and took data from 2008 to 2012 with the CNGS neutrino beam from CERN. After the discovery of ντντ appearance in 2015, with 5.1σ5.1σ significance, the criteria to select ντντ candidates have been extended and a multivariate approach has been used for events identification. In this way the statistical uncertainty in the measurement of the oscillation parameters and of ντντ properties has been improved. Results are reported.

Abstract

OPERA is a long-baseline experiment designed to search for νμ→ντνμ→ντ oscillations in appearance mode. It was based at the INFN Gran Sasso laboratory (LNGS) and took data from 2008 to 2012 with the CNGS neutrino beam from CERN. After the discovery of ντντ appearance in 2015, with 5.1σ5.1σ significance, the criteria to select ντντ candidates have been extended and a multivariate approach has been used for events identification. In this way the statistical uncertainty in the measurement of the oscillation parameters and of ντντ properties has been improved. Results are reported.
