生成的结果可以用 pythia.event 和 pythia.process 查看。

1、mypythia.event is a  vector (or a list) of Particle object.

mypythia.event.size();                                       // 0 < i < event.size().
mypythia.event.list();                                       // provide event listing.
mypythia.event.list(ostream& os);                            // 输出 list
mypythia.event.list(bool showScaleAndVertex, bool showMothersAndDaughters = false);
mypythia.event.list(bool showScaleAndVertex, bool showMothersAndDaughters, ostream& os);
                                                             // showScaleAndVertex: 显示每个量单位
                                                             // os (default = cout) ostream 的引用
mypythia.event.motherList(i), daughterList(i), sisterList(); // a vector<int> of mothers, daughters, sisters.
mypythia.event.iTopCopy(i), iBotCopy(i);                     // top or bottom “carbon copy”.

2、mypythia.process: hard subprocess, roughly like Les Houches

pythia.process.list() 的结果:

3、pythia.statistics() 统计各个过程的截面以及程序过程中的问题。

mypythia.statistics();
mypythia.statistics(bool all = false, bool reset = false);
                       //
