Neutral current neutrino oscillation via quantum field theory approach

Neutrino and anti-neutrino states coming from the neutral current or \(Z_0\) decay are blind with respect to the flavor. The neutrino oscillation is observed and formulated when its flavor is known. However, it has been shown that we can see neutrino oscillation pattern for \(Z_0\) decay neutrinos p...

Summary:Neutrino and anti-neutrino states coming from the neutral current or \(Z_0\) decay are blind with respect to the flavor. The neutrino oscillation is observed and formulated when its flavor is known. However, it has been shown that we can see neutrino oscillation pattern for \(Z_0\) decay neutrinos provided that both neutrino and anti-neutrino are detected. In this paper, we restudy this oscillation via quantum field theory approach. Through this approach, we find that the oscillation pattern ceases if the distance between the detectors is larger than the coherence length, while both neutrino and antineutrino states may be coherent. Also the uncertainty of source (region of \(Z_0\) decay) does not have any role in the coherency of neutrino and antineutrino.
