In fact, no neutrinos at all are observed at the Cern end: just the protons that produce the pions that produce the neutrinos. An upcoming experiment at Fermilab will observe neutrinos at both ends (the far end will be in Minnesota). -- John Hasler jhas...@newsguy.com Dancing Horse Hill Elmwood, WI USA _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
