英文摘要 | The search for an additional heavy gauge boson z' is described. the models considered are based on either a superstring-motivated e6 or on a left-right symmetry and assume a minimal higgs sector. cross sections and asymmetries measured with the l3 detector in the vicinity of the z resonance during the 1990 and 1991 running periods are used to determine limits on the z-z' gauge boson mixing angle and on the z' mass. for z' masses above the direct limits, we obtain the following allowed ranges of the mixing angle, theta(m), at the 95% confidence level: -0.004 less-than-or-equal-to theta(m) less-than-or-equal-to 0.015 for the chi model, -0.003 less-than-or-equal-to theta(m) less-than-or-equal-to 0.020 for the psi model, -0.029 less-than-or-equal-to theta(m) less-than-or-equal-to 0.010 for the eta model, -0.002 less-than-or-equal-to theta(m) less-than-or-equal-to 0.015 for the lr model. |
