This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors performed a direct search for the anomalous ZZ[gamma] and Z[gamma][gamma] couplings by studying p[anti p][yields][ell][ell][gamma]+ X, ([ell]= e, [mu]) events at[radical]s= 1.8 TeV with the D0 detector at the Fermilab Tevatron Collider. A fit to the transverse energy spectrum of the photon in the signal events, based on the data set corresponding to an integrated luminosity of 14.3 pb[sup[minus]1] (13.7 pb[sup[minus]1]) for the electron (muon) channel, yields the following 95% confidence level limits on the anomalous CP-conserving ZZ[gamma] couplings:[vert-bar]h[sub 30][sup Z][vert-bar]
