Limits on anomalous triple gauge couplings in p(p)over-bar collisions at sqrt{s}=1.96 TeV (2007)

Abstract
8 pages, 3 figures.-- PACS nrs.: 12.15.Ji, 13.40.Em, 14.70.Fm, 14.70.Hp.-- ISI Article Identifier: 000251987200003.-- ArXiv pre-print available at: http://arxiv.org/abs/0705.2247. We present a search for anomalous triple gauge couplings (ATGC) in WW and WZ boson production. The boson pairs are produced in p(p)over-bar collisions at sqrt{s} = 1.96 TeV, and the data sample corresponds to 350 pb(-1) of integrated luminosity collected with the CDF II detector at the Fermilab Tevatron. In this search one W decays to leptons, and the other boson (W or Z) decays hadronically. Combining with a previously published CDF measurement of Wγ boson production yields ATGC limits of -0.18 < λ < 0.17 and -0.46 < Δκ < 0.39 at the 95% confidence level, using a cutoff scale Λ = 1.5 TeV..
