The Process Classification Scheme

A wide selection of fundamental $2 \to 1$ and $2 \to 2$ tree processes of the Standard Model (electroweak and strong) has been included in PYTHIA, and slots are provided for many more, not yet implemented. In addition, `minimum-bias'-type processes (like elastic scattering), loop graphs, box graphs, $2 \to 3$ tree graphs and many non-Standard Model processes are included. The classification is not always unique. A process that proceeds only via an

-channel state is classified as a $2 \to 1$ process (e.g. $\mathrm{q}\overline{\mathrm{q}}\to \gamma^* / \mathrm{Z}^0\to \mathrm{e}^+\mathrm{e}^-$ ), but a $2 \to 2$ cross section may well have contributions from

-channel diagrams ( $\mathrm{g}\mathrm{g}\to \mathrm{g}\mathrm{g}$ obtains contributions from $\mathrm{g}\mathrm{g}\to \mathrm{g}^* \to \mathrm{g}\mathrm{g}$ ). Also, in the program, $2 \to 1$ and $2 \to 2$ graphs may sometimes be convoluted with two $1 \to 2$ splittings to form effective $2 \to 3$ or $2 \to 4$ processes ( $\mathrm{W}^+ \mathrm{W}^- \to \mathrm{h}^0$ is folded with $\mathrm{q}\to \mathrm{q}'' \mathrm{W}^+$ and $\mathrm{q}' \to \mathrm{q}''' \mathrm{W}^-$ to give $\mathrm{q}\mathrm{q}' \to \mathrm{q}'' \mathrm{q}''' \mathrm{h}^0$ ).

The original classification and numbering scheme feels less relevant today than when originally conceived. In those days, the calculation of $2 \to 3$ or $2 \to 4$ matrix elements was sufficiently complicated that one would wish to avoid it if at all possible, e.g. by having in mind to define effective parton densities for all standard model particles, such as the $\mathrm{W}^{\pm}$ . Today, the improved computational techniques and increased computing power implies that people would be willing to include a branching $\mathrm{q}\to \mathrm{q}\mathrm{W}$ as part of the hard process, i.e. not try to factor it off in some approximation. With the large top mass and large Higgs mass limits, there is also a natural subdivision, such that the $\b$ quark is the heaviest object for which the parton distribution concept makes sense. Therefore most of the prepared but empty slots are likely to remain empty, or be reclaimed for other processes.

It is possible to select a combination of subprocesses to simulate, and also afterwards to know which subprocess was actually selected in each event. For this purpose, all subprocesses are numbered according to an ISUB code. The list of possible codes is given in Tables

and

. Only processes marked with a `+' sign in the first column have been implemented in the program to date. Although ISUB codes were originally designed in a logical fashion, we must admit that subsequent developments of the program have tended to obscure the structure. For instance, the process numbers for Higgs production are spread out, in part as a consequence of the original classification, in part because further production mechanisms have been added one at a time, in whatever free slots could be found. At some future date the subprocess list will therefore be re-organized. In the thematic descriptions that follow the main tables, the processes of interest are repeated in a more logical order. If you want to look for a specific process, it will be easier to find it there.
