Abstract
The total hadronic cross section in e(+)e(-) annihilation was measured at root s = 57.77 GeV to be sigma(h) = 143.6 +/- 1.5(stat) +/- 4.5(sy s) pb with only the QED corrections. The measurement was based on data corresponding to an integrated luminosity of 90.8 pb(-1) accumulated by the TOPAZ detector at TRISTAN. Our data point put stringent constra ints on the size of the gamma-Z(0) interference and the Z(0) mass. Com bining our data with the OPAL data at LEP, we obtained the coefficient of the interference and the Z(0) mass to be J(had) = 0.10 +/- 0.26 an d ($) over bar M(Z) = 91.151 +/- 0.008 GeV, respectively, in a model-i ndependent analysis.
