The model describes spectral indices, fluxes and the duration of the high-energy component as well as a long keV tail present in the prompt phase of GRB980923. Here, we present an extension of this model to describe the high-energy emission of GRB090926A. We argue that the emission consist of two components, one with a duration less than 1s during the prompt phase, and a second, longer-lasting GeV phase lasting hundred of seconds ","authors_text":"J.
