Abstract
The total hadronic cross section in e + e − annihilation has been measured at s = 57.77 GeV using 290 pb −1 data sample collected with the VENUS detector at KEK TRISTAN. The cross section obtained is 140.3 ±1.8 pb for s′/ s≥0.5, where s′ is the square of the invariant mass of the final state hadrons. The present result together with the recent results from the LEP collaborations is used to determine the hadronic γ− Z 0 interference parameter, j tot had, to be 0.196±0.083. The result is in good agreement with the Standard Model prediction of 0.220.
