Compositeness scenarios may also give rise to sharp resonances of excited quarks and leptons. An excited copy of the first generation is implemented, consisting of spin particles (code 4000001), (4000002), (4000011) and (4000012). A treatment of other generations is not currently possible.
The current implementation contains gauge interaction production by quark-gluon fusion (processes 147 and 148) or lepton-photon fusion (process 146) and contact interaction production by quark-quark or quark-antiquark scattering (processes 167-169) . The couplings , and to the SU(2), U(1) and SU(3) groups are stored in RTCM(43) - RTCM(45), the scale parameter in RTCM(41); you are also expected to change the masses in accordance with what is desired -- see [Bau90] for details on conventions. Decay processes are of the types , , or , with the latter three (two) available also for ( ). A non-trivial angular dependence is included in the decay for processes 146-148, but has not been included for processes 167-169.
