The proton beam was directed toward OPERA, so the ricocheting neutrinos had roughly the same direction by conservation of momentum. All of the other reaction products were absorbed along the 800km of rock between source and detector.

But that particular neutrino beam (CGNS) only ran from 2005 to 2012, and I’m not sure what they’re using now.

And isn’t it hard to “aim” them to point to some observatory on the other side of the planet?

Also, are there any parameters in the “SM+neutrino oscillation” model that are as yet unmeasured?
