# What type of neutrinos do we detect

There are three types of neutrinos known today. When detecting them, how can we tell which type we are detecting?

Neutrino flavor is defined as agreeing with the flavor of the charged lepton participating in the interaction, so that the neutrino in the reaction $$\nu + A \to \mu + X \,,$$ is defined to be a muon neutrino and the one in $$\nu + n \to e + p$$ is a electron neutrino by definition.
