GENXICC2:用于重子强子产生的Generator的升级版本$Ξ_{cc}$,$Ξ_{bc}$和$Ξ_{bb}$

GENXICC2.0: An Upgraded Version of the Generator for Hadronic Production of Double Heavy Baryons $Ξ_{cc}$, $Ξ_{bc}$ and $Ξ_{bb}$

Chao-Hsi Chang, Jian-Xiong Wang, Xing-Gang Wu

摘要:

本文介绍了GENXICC({ \bf A Generator for Hadronic Production of the Double Heavy Barons $Ξ_{cc}$,$Ξ_{bc}$ and $Ξ_{bb}$ by C.H. Chang,J.X. Wang和X.G.吴,} [其第一个版本:在计算。物理通讯{ \bf 177}(2007)467-478])。该版本在PYTHIA和GNU C编译器中实现,用户可以方便地在各种实验环境中模拟生产的全部事件。与前一版本相比,为了在PYTHIA中正确地实现它,补充了一个将产生的重双夸克分裂成相应重子的子程序,并相应地改变了生成元到PYTHIA的相间。在子程序中,解释,某些必要的假设(近似),以便保存的动量和QCD“色”流的碎片。

英文摘要:

An upgraded (second) version of the package GENXICC ({\bf A Generator for Hadronic Production of the Double Heavy Baryons $Ξ_{cc}$, $Ξ_{bc}$ and $Ξ_{bb}$ by C.H. Chang, J.X. Wang and X.G. Wu,} [its first version: in Comput. Phys. Commun. {\bf 177} (2007) 467-478]) is presented. Users, with this version being implemented in PYTHIA and a GNU C compiler, may simulate full events of the production in various experimental environments conveniently. In comparison with the previous version, in order to implement it in PYTHIA properly, a subprogram for the fragmentation of the produced double heavy diquark to the relevant baryon is complemented and the interphase of the generator to PYTHIA is changed accordingly. In the subprogram, with explanation, certain necessary assumptions (approximations) are made so as to conserve the momenta and the QCD `color' flow for the fragmentation.
