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.

Comments: 27 pages, 8 figures, an article on a M.C. generator (the relevant program is not involved but it can be obtained from the authors). submitted to CPC
