A theoretical study on the plasmon-polariton modes coupled with a fast electron beam inside a metallic single-walled carbon nanotube is presented. The Maxwell's equations coupled with a linearized hydrodynamic model for the nanotube's charge oscillations are used. By considering the electron beam effects, general expression of dispersion relation of electromagnetic modes on nanotube's surface is obtained. It is shown numerically that by considering the electron beam effects, the polariton frequency shifts to lower values.
