Abstract: Generation of complete events containing very high pt jets

The study of very high transverse momentum jets will be an important issue at the LHC, in particular since the corresponding cross sections will be considerably larger than at RHIC energies. Jets are expected to provide information on the QGP formation, due to the energy loss of fast partons in the medium. Jet cross sections can be in principle compared to simple pQCD calculations, based on the hypothesis of factorization. But often it is useful or even necessary to not only compute the production rate of the very high pt jets, but in addition the "rest of the event". The proposed talk is based on recent work, where we try to construct an event generator -- fully compatible with pQCD -- which allows to compute complete events, consisting of high pt jets plus all the other low pt particles produced at the same time. Whereas in "generators of inclusive spectra" like Pythia one may easily trigger on high pt phenomena, this is not so obvious for "generators of physical events", where in priciple one has to generate a very large number of events in order to finally obtain rare events (like those with a very high pt jet). I will discuss how we overcome these difficulties in the framework of the EPOS model.
