3<h2>SUSY Processes</h2>

5The implementation of SUSY processes is barely begun, so this page
6is more a placeholder than a repository of useful processes.

9Here is collected processes involving supersymmetric particle
10production, with the exception of the (extended) Higgs sector.
11Since the number of separate but closely related processes is so big,
12there will not be switches for each separate process but only for a
13reasonable set of subgroups.

15<br/><note>Important note:</note>
16In order to simulate SUSY processes it is required to read in the
17couplings and masses relevant for the scenario to be studied. This
18is done with the help of the SUSY Les Houches Accord (SLHA). The
19reading of a relevant SLHA file <b>must</b> be set up, as described
20on <aloc href="SUSYLesHouchesAccord">this page</aloc>.

28Pair production of neutralinos by quark-antiquark annihilation. With
29four neutralino species this gives ten separate processes, codes
301201 - 1210. Neutralino decays have not yet been implemented.
