Constraints on the Mass and Mixing of Z'-bosons from LEP2 Experimental Data

Abstract

Analysis of effects induced by Z'-bosons based on LEP2 exper­imental data (OPAL, DELPHI, ALEPH, L3) on differential cross sections of the W±-pair production process was performed. Constraints on Z'-boson mass Mz' and Z — Z' mixing angle ф were obtained for some specific extended gauge models.
