and exotic quarks in several different RS models. The total width also sensitively depends on the couplings, and how many custodial partners are available as decay modes. The width is generally large, owing to the strong couplings present, and it may be possible to reconstruct it from the final state invariant mass distributions, which would also allow one to use it as an additional source of information. The final column of Table \[tab:brs\] shows the total width $\Gamma_{g^1} / M_{g^1}$ for each model. Variations are typically around $5\%$, with the exception of the model with an extra custodial partner, whose very strong coupling has a big effect on the width. In fact, allowing too many additional custodial partners will rapidly drive $\Gamma_{g^1} \gtrsim M_{g^1}$, an indication of a break-down of perturbation theory. From Eq. (\[decayequation\]), we can infer that there can be at most four new custodial quarks whose masses are less than $M_{g^1} / 2$.
