In neutrino oscillation experiment, for example NOvA [but it could be other if you prefer], what are the diagrams involved for the detection of the neutrino in the detector ?
I have explored inside many PhD theses to understand a bit, but none are very clear, and the authors seem not really to master the physics of the interaction at the detector (they seem to just copy/paste the explanation on the previous theses, etc.), and none are exhaustive for the involved interactions.
Here are the diagrams that I have created with jaxodraw and that is a synthesis of those diagrams that I found from various documents.
My question is : for detecting the resulting oscillated neutrino at the far distance detector :
-which of these diagrams (maybe there are additive ones ?) correspond to the signal ?
-which correspond to the background ?
In particular, do elastic scattering contribute to the signal ? (authors of PhD theses most often skip the purely elastic diagrams, for unknown reason)
Do neutral current contribute to the signal (for example elastic netural current)
By the way : QE=quasi elastic, RES=resonant production of pions, DIS=deep inelastic scattering, COH=coherent production of pions.
