摘要

The very hard. gamma-ray spectrum from distant blazars challenges the traditional synchrotron self-Compton ( SSC) model, which may indicate that there is a contribution from an additional high-energy component beyond the SSC emission. In this paper, we study the possible origin of the hard gamma-ray spectrum from distant blazars. We develop a model to explain the hard gamma-ray spectrum from blazar 1ES 1101-232. In the model, the optical and X-ray radiation would come from the synchrotron radiation of primary electrons and secondary pairs and the GeV emission would be produced by the SSC process, however, the hard. -ray spectrum would originate from the decay of neutral pion produced through proton-photon interactions with the synchrotron radiation photons within the jet. Our model can explain the observed spectral energy distribution of 1ES 1101-232 well, especially the very hard gamma-ray spectrum. However, our model requires a very large proton power to efficiently produce the. -ray through proton-photon interactions.
