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

Abstract

We write down a generator program for the hadronic production of the double-heavy baryons $\Xi_{cc}$, $\Xi_{bc}$ and $\Xi_{bb}$ 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.
