GENXICC: A Generator for Hadronic Production of the Double Heavy Baryons $Ξ_{cc}$, $Ξ_{bc}$ and $Ξ_{bb}$

Abstract

We write down a generator program for the hadronic production of the double-heavy baryons $Ξ_{cc}$, $Ξ_{bc}$ and $Ξ_{bb}$ according to relevant publications. We name it as GENXICC and we test it by comparing its numerical results with those in references. It is written in a PYTHIA-compatible format and it can be easily implemented into PYTHIA. GENXICC is also written in modularization manner, with {\bf make}, a GNU C compiler, one may apply the generator to various situations or experimental environments very conveniently.
