We report the first direct observation of neutrino interactions at a particle collider experiment. Neutrino candidate events are identified in 13.6 TeV center-of-mass energy pp collision dataset 35.4 fb^{-1} using active electronic components FASER detector Large Hadron Collider. The candidates required to have track propagating through entire length and be consistent with muon charged-current interaction. infer 153_{-13}^{+12} significance 16 standard deviations above background-only...
Important open questions are still present in fundamental Physics and Cosmology, like the nature of Dark Matter, matter-antimatter asymmetry validity Standard Model particle interactions. Addressing these requires a new generation massive detectors to explore subatomic astrophysical worlds. ICARUS T600 is first large mass (760 tons) example able combine imaging capabilities old famous ``bubble chamber'' with excellent energy measurement huge electronic detectors. now operates at Gran Sasso...

The CERN-SPS accelerator has been briefly operated in a new, lower intensity neutrino mode with ~10^12 p.o.t. /pulse and beam structure made of four LHC-like extractions, each narrow width 3 ns, separated by 524 ns. This very tightly bunched represents substantial progress respect to the ordinary operation CNGS beam, since it allows accurate time-of-flight measurement neutrinos from CERN LNGS on an event-to-event basis. ICARUS T600 detector collected 7 beam-associated events, consistent...
