• Feb 21 2003: talk at Fermilab W&C seminar

summary of the results: Feb'2003 (integrated luminosity: 72.0+/-4.3 pb^-1)

• W tau nu cross section measurement

         sigma(ppbar->W)*BR(W->tau nu) = 2.62+/-0.07(stat)+/-0.21(syst)+/-0.16(lum)
         BR(W->tau nu)/BR(W->e nu)     = 0.99+/-0.04(stat)+/-0.07(syst)
  

• from the ratio of BR's one can derive the ratio of the coupling constants:

          g(tau)/g(e) = 0.99+/-0.02(stat)+/-0.04(syst)
