S054CTL
Lepton universality assumed. Limits are for $\Lambda_{LL}^{\pm}$ only. For other cases, see each reference.

1  SCHAEL 2007A limits are from $\mathit R_{c}$, $\mathit Q{}^{depl}_{FB}$, and hadronic cross section measurements.
2  ABBIENDI 2004G limits are from ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \ell}^{+}}{{\mathit \ell}^{-}}$ cross section at $\sqrt {s }$ = $130 - 207~$GeV.
3  BABICH 2003 obtain a bound $-0.175$ TeV${}^{-2}<1/\Lambda {}^{2}_{\mathit LL}$ $<0.095$ TeV${}^{-2}$ (95$\%$CL) in a model independent analysis allowing all of $\Lambda _{\mathit LL}$, $\Lambda _{\mathit LR}$, $\Lambda _{\mathit RL}$, $\Lambda _{\mathit RR}$ to coexist.
