A classical fluid description is used to investigate nonlinear interactions between an electron-type neutrino burst and a collisionless magnetized electron-positron plasma. It is found that the symmetry between the electron and positron dynamics is broken due to the presence of intense neutrino bursts. The latter can excite strong upper-hybrid wakefields, which can produce unlimited acceleration of pairs across the external magnetic field direction via a surfatron mechanism. Implications of our results to the production of high-energy electrons and positrons in astrophysical environments are discussed.
