Study of E+ E- --> MU+ MU-, E+ E- --> TAU+ TAU- and E+ E - -->HADRONS. This paper presents new results on R and the asymmetry for sqrt(s) 61.4 to 64.0 and combines with previously published VENUS data to give an exper imental limit of 426 GeV (90% CL.) for the mass of an extra-Z boson produced in the annihilation interaction.; CR. = The pure R-ratios were published by the authors. The measured cross sectio ns were corrected for ISR/FSR, initial and final state QED and EW loops, box di agrams. (NP B263, 347 (1986)). ATTENTION! The original correction assumed M(Z) = 91.1 GeV, M(TQ) = 100 GeV, M(HIGGS) = 100 GeV. We additionally corrected the data according to the current values M(Z) = 91.187 GeV, M(TQ) = 174.3 GeV, M(HIGGS ) = 115 GeV using the ZFITTER routine; SB = ENCODED 3 APR 2004 BY ZOV; DS = CORRECTED:EW; AC = KEK-TRISTAN; DE = VENUS; COL = VENUS Collaboration; DS. = RAD:FULL; DS. = RPP-2019; DS. = RPP-2021; DSC = Radiative correction includes ISR and vacuum polarisation; DSC. = QUESTION: rescale using up-to-date total cross section data?; SB. = UPDATED 27 DEC 2019 BY ZOV; DS. = EE-2024::FS:2hadron (hadrons)::RAD:full::WEIGHT:::COMMENT:; DS. = EE-2025::FS:2hadron (hadrons)::RAD:full::WEIGHT:::COMMENT:; DS. = EE-2026::FS:2hadron (hadrons)::RAD:full::WEIGHT:::COMMENT:; SB. = UPDATED 07 DEC 2024 BY ZOV; *E
