Abstract

Following the strict single particle approach, when collective effects are not considered, electron-positron plasma flow in pulsar magnetospheres may reach very high energies, and therefore become quasi-classical as charged particles have stochastic trajectories due to the radiation of very high energy photons, in the hard gamma-ray domain. The associated energy balance imposes an upper limit on the energy of the radiated photons, well below the TeV range. However such an upper limit might be enhanced provided the quasi-classical single particle approach incorporates collective effects, namely the ones produced in the plasma rest frame.
