A bstractIn spring 2012 CERN provided two weeks of a short bunch proton beam dedicated to the neutrino velocity measurement over a distance of 730 km. The OPERA neutrino experiment at the underground Gran Sasso Laboratory used an upgraded setup compared to the 2011 measurements, improving the measurement time accuracy. An independent timing system based on the Resistive Plate Chambers was exploited providing a time accuracy of ~1 ns. Neutrino and anti-neutrino contributions were separated using… 

New results of the OPERA long-baseline experiment in the CNGS neutrino beam
