...run

There is still some discrepancy in A_LR from the SM prediction. This is mostly from upward fluctuations in the 1993 and 1996 data. The preliminary results from 1997, $A_{LR} = 0.1475 \pm 0.0042 \pm 0.0016$, and 1998, $A_{LR} = 0.1487 \pm 0.0031 \pm 0.0017$, are in excellent agreement.

...only

The invisible width, $\Gamma({\rm inv})$, constrains the number, $N_\nu$, of standard neutrino flavors. A fit to all data with $N_\nu$ free yields $N_\nu = 2.992 \pm 0.011$.

Note, that the $R^{\bar{\nu}}$ component introduces a larger m_t dependence compared to earlier DIS measurements, such as from CCFR.

For comparison, the LEPEWWG [9] quotes $\alpha_s = 0.119 \pm 0.003$.

...correlation

$\rho_0$ is also strongly anticorrelated with $\alpha_s$ ($-53\%$) and m_t ($-46\%$).

...SM

Thus, our definition differs somewhat from the original definition [77] which included the m_t and M_H contributions to the self-energies in S , T , and U .
