摘　　要：The presence of background classical sources affects quantum field theory significantly in different ways.Neutrino oscillation is a phenomenon that confirms that neutrinos are massive fermions in nature,a celebrated result in modern physics.Neutrino oscillation plays an important role in many astrophysical observations.However,the interactions between the background classical sources with neutrinos are not often considered.In the present article,we show the effect of some classical sources,namely matter currents,electromagnetic waves,torsion,and gravitational waves on neutrino oscillation.It is shown explicitly that the above sources can change the helicity state of neutrinos during neutrino oscillation.
