No, I'm not referring to elastic scattering. It's the positron that they are tracking, and it moves in approximately the same direction as the neutrino to conserve linear momentum. It's exactly the same process, the only difference is anti-neutrinos produce positrons, neutrinos produce electrons.
- snophysics 4y agoI don't think that's true. The energies of the neutrinos they are looking at are relative low (less than 15 MeV), and according to https://journals.aps.org/prd/pdf/10.1103/PhysRevD.60.053003 https://journals.aps.org/prd/pdf/10.1103/PhysRevD.60.053003 the positron is isotropic around 15 MeV and is only forward pointing at much higher energies.
