摘要：

Recent analyses of precision low energy electroweak data indicate that the deviation from the Standard Model predict ions of the measurement of atomic parity violation (2.3 sigma), the effective number of massless neutrinos (2 sigma), and A(b) (2.7 sigma) could be better described if the existence of an extra Z' neutral gauge boson is assumed. We investigate the implications of a 300- 00 GeV/c(2) extra Z' on current p (p) over bar collider data at roots = 1.8 TeV, including the forward-backward charge asymmetry for very high mass e(+)e(-) pairs, and the invariant mass specstrum of high mass e(+)e(-), mu (+),mu (-) t (t) over bar and b (b) over bar pairs. For example, a 500 GeV/c(2) Z' with a total production cross section of approximate to 3 pb and enhanced coupling to the third generation, better describes both the low energy and the Tevatron data.
