The results of a search for W boson pair production in p[bar p] collisions at[radical]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[plus-minus] 0.13 events with an integrated luminosity of approximately 14 pb[sup[minus]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[minus]2.6

The authors present results of a search for diphoton resonances produced inclusively and in association with a vector boson using 100 pb[sup[minus]1] of p[anti p] collisions using the CDF detector. They set upper limits on the product of cross section times branching ratio for p[anti p][r-arrow][gamma][gamma][r-arrow] X and p[anti p][r-arrow][gamma][gamma][r-arrow] W/Z. Using a NLO prediction for associated production cross section of a Higgs with a vector boson (W or Z), they set an upper limit on the branching ratio for H[r-arrow][gamma][gamma]. They set a lower limit on the mass of a'bosophilic' Higgs boson (e.g. one which couples only to[gamma], W, and Z bosons with Standard Model couplings) of 82 GeV/c[sup 2] at 95% C.L.

We present results on a search for a heavy charged vector boson, W', decaying to an electron-neutrino pair in p{bar p} collisions at {radical}s = 1.96 TeV using a data sample corresponding to an integrated luminosity of 205 pb{sup -1}. We found no evidence of this decay channel, and set 95% confidence level limits on the production cross section times branching fraction assuming the light neutrino. We also set the limit on the W' boson mass at M{sub W'}> 788 GeV/c{sup 2}, assuming the standard model strength couplings.
