Observation of $$W^{+} W^{-}$$ Production in $$p \bar{p}$$ Collisions at 1.8-TeV
- Univ. of Wisconsin, Madison, WI (United States)
A search for w+w- production in $$p\overline{p}$$ collisions at $$\sqrt{s}$$ = 1.8 TeV is presented. In a data sample of 108 $$pb^{-1}$$ recorded with the Collider Detector at Fermilab (CDF), five $$W^{+}W^{-}$$ candidates are observed in the dilepton channel $$W^{+}W^{-} \to \zeta^{+} \zeta^{-} \nu\overline{\nu}$$. We expect 3.53$$ \pm$$ 1.24 events from the electroweak $$W^{+}W^{-}$$ production and 1.21$$ \pm$$ 0.30 events from various backgrounds. The $$W^{+}W^{-}$$ production cross section is found to be $$\sigma(p\overline{p} \to W^{+}W^{-}$$) = $$10.2^{+6.3}_{-5.1}$$(stat) $$\pm$$ 1.6(syst) ph. Then limits on boson anomalous couplings are set at 95% confidence level.
