Abstract: A measurement of vector boson (V) production in conjunction with a D*(2010)(+) meson is presented. Using a data sample corresponding to 9.7 fb(-1) of proton-antiproton collisions at center-of-mass energy root s = 1.96 TeV produced by the Fermilab Tevatron, we reconstruct V + D*+ samples with the CDF II detector. The D*+ is fully reconstructed in the D*(2010)(+) -> D-0 (-> K-pi(+))pi(+) decay mode. This technique is sensitive to the associated production of vector boson plus charm or bottom mesons. We measure the ratio of production cross sections sigma(W + D*) = sigma(W) = [1.75 +/- 0.13(stat) +/- 0.09(stat)]% and sigma(Z + D*)/sigma(Z) = [1.5 +/- 0.4(stat) +/- 0.2(stat)]% and perform a differential measurement of d sigma(W + D*)/dp(T)(D*). Event properties are utilized to determine the fraction of V + D*(2010)(+) events originating from different production processes. The results are in agreement with the predictions obtained with the PYTHIA program, limiting possible contribution from non-standard-model physics processes.
