Resumen:
Aims. We study the production of VHE emission in blazars as a superposition of a steady component from a baryonic jet, and atime-dependent contribution from an inner e− e+ beam launched by the black hole.Methods. Both primary relativistic electrons and protons are injected in the jet, and the particle distributions along it are found bysolving a one-dimensional transport equation accounting for convection and cooling. The short-timescale variability of the emissionis explained by local pair injections in turbulent regions of the inner beam.Results. For illustration, we apply the model to the case of PKS 2155-304, reproducing a quiescent state of emission with inverseCompton and synchrotron radiation from primary electrons, as well as proton-proton interactions in the jet. The latter also yieldan accompanying neutrino flux that could be observed with a new generation km-scale detector in the northern hemisphere such asKM3NeT.
