Excited fermions

ISUB =

146	$\mathrm{e}\gamma \to \mathrm{e}^*$
147	$\d\mathrm{g}\to \d ^*$
148	$\u\mathrm{g}\to \u ^*$
167	$\mathrm{q}_i \mathrm{q}_j \to \mathrm{q}_k \d ^*$
168	$\mathrm{q}_i \mathrm{q}_j \to \mathrm{q}_k \u ^*$
169	$\mathrm{q}_i \overline{\mathrm{q}}_i \to \mathrm{e}^{\pm} \mathrm{e}^{*\mp}$

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 $1/2$ particles $\d ^*$ (code 4000001), $\u ^*$ (4000002), $\mathrm{e}^*$ (4000011) and $\nu^*_{\mathrm{e}}$ (4000012).

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 $f$, $f'$ and $f_s$ to the SU(2), U(1) and SU(3) groups are stored in RTCM(43) - RTCM(45), the scale parameter $\Lambda$ in RTCM(41); you are also expected to change the $\mathrm{f}^*$ masses in accordance with what is desired -- see [Bau90] for details on conventions. Decay processes are of the types $\mathrm{q}^* \to \mathrm{q}\mathrm{g}$, $\mathrm{q}^* \to \mathrm{q}\gamma$, $\mathrm{q}^* \to \mathrm{q}\mathrm{Z}^0$ or $\mathrm{q}^* \to \mathrm{q}' \mathrm{W}^{\pm}$, with the latter three (two) available also for $\mathrm{e}^*$ ( $\nu^*_{\mathrm{e}}$). A non-trivial angular dependence is included in the $\mathrm{q}^*$ decay for processes 146-148, but has not been included for processes 167-169.
