GENXICC2.1: An Improved Version of GENXICC for Hadronic Production of Doubly Heavy Baryons

Abstract

We present an improved version of GENXICC, which is a generator for hadronic production of the doubly heavy baryons ${\Xi }_{cc}$, ${\Xi }_{bc}$ and ${\Xi }_{bb}$ and has been raised by C.H. Chang, J.X. Wang and X.G. Wu [Comput. Phys. Commun. 177 (2007) 467; Comput. Phys. Commun. 181 (2010) 1144]. In comparison with the previous GENXICC versions, we update the program in order to generate the unweighted baryon events more effectively under various simulation environments, whose distributions are now generated according to the probability proportional to the integrand. One Les Houches Event (LHE) common block has been added to produce a standard LHE data file that contains useful information of the doubly heavy baryon and its accompanying partons. Such LHE data can be conveniently imported into PYTHIA to do further hadronization and decay simulation, especially, the color-flow problem can be solved with PYTHIA8.0.
