摘要：

The results of a search for W boson pair production in p (p) over bar collisions at root s = 1.8 TeV with subsequent decay to dilepton (e mu, ee, and mu mu) channels are presented. One event is observed with an expected background of 0.56 +/- 0.13 events with an integrated luminosity of approximately 14 pb(-1). Assuming equal strengths for the WWZ and WW gamma gauge boson coupling parameters kappa and lambda, limits on the CP-conserving anomalous coupling constants are -2.6 < Delta kappa < 2.8 and -2.1 < lambda < 2.1 at the 95% confidence level.
