$R_{b}$ measurements at centre-of-mass energy above the Z pole at LEP
The measurements of R/sub b/= sigma (e/sup +/e/sup -/ to bb)/ sigma (e/sup +/e/sup -/ to qq) at centre-of-mass energies above the Z pole using data collected by the LEP experiments from 1995 to 1999 are summarised. The measurements are performed using b-tagging methods that exploit the relatively la...
