Fitting fixed-target and ion collisions in the LHCb Gauss simulation framework

Abstract

The LHCb experiment has been operating in various beam configurations in Run 1 and 2 of the LHC, with collisions of lead ion beams or in a fixed-target setup. In order to analyse these data, the Gauss simulation software has been extended to be able to generate events describing these configurations, based mainly on the EPOS event generator. These proceedings give details about the methods employed.
