Measurement of the azimuthal angle distribution of leptons from <em><strong>W</strong></em> boson decays as a function of the <em><strong>W</strong></em> transverse momentum in <em>pp</em> collisions at s√=1.8  TeV

Using theoretical predictions assuming the manifest left- right symmetric model, which has the right-handed CKM matrix and the gauge coupling constant identical to those of the

For the lepton jets sample with two b-tagged jets, the two possible M 2 ‘b values of the charged lepton with either the highest or the second highest E T b-tagged jet are used

Combining this result with a previous CDF measurement obtained using electrons in the central region (jj &amp; 1), we present the first measurement of the ratio of central-electron

We present the first measurement of the production cross section of a W boson with a single charm quark (c) in pp collisions at s√=1.96  TeV, using soft muon tagging of c jets.. In

Systematic uncertainties on the m Z measurement result from the E=p calibration (29 MeV), calorimeter nonline- arity measurement (23 MeV), and higher-order QED ra- diation (14

Sources of systematic uncertainty in the background yield of tagged b jets include the uncertainty in the b -jet tagging efficiency in the data (a relative 6% uncertainty on all
