SUSY Processes

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

The processes in this set are not yet fully handled.

Important note: In order to simulate SUSY processes it is required to read in the couplings and masses relevant for the scenario to be studied. This is done with the help of the SUSY Les Houches Accord (SLHA). The reading of a relevant SLHA file must be set up, as described on this page.

flag name="SUSY:all" default="off"
Common switch for production of supersymmetric particles, i.e. particles with R-parity -1.

flag name="SUSY:qqbar2chi0chi0" default="off"
Pair production of neutralinos by quark-antiquark annihilation. With four neutralino species this gives ten separate processes, codes 1001 - 1010. The current implementation is in a development stage and does not include contributions from diagrams with intermediate squarks, hence the correct answer is only obtained in the limit of infinitely heavy squarks. As yet, there are also no sparticle decays implemented - all neutralinos decay to Gravitino+photon.
