Physics at CNGS neutrino beam

The CERN Neutrinos to Gran Sasso project (CNGS) is devoted to prove unambiguously the νμ→ντ oscillation channel in the atmospheric sector. The high energy and high intensity CNGS muon neutrino beam, generated at CERN, is directed towards the Gran Sasso National Laboratory (LNGS), in Italy, where the ICARUS and OPERA long base-line experiments search for ντ appearance. In this talk, a review of the status and physics potential of the CNGS program will be presented. A detailed discussion about recent results obtained by the OPERA Collaboration will be given, too.
