Abstract
A measurement of vector boson (V) production in conjunction with a D[superscript *](2010)[superscript +] meson is presented. Using a data sample corresponding to 9.7 fb[superscript -1] of proton-antiproton collisions at center-of-mass energy √s = 1.96 TeV produced by the Fermilab Tevatron, we reconstruct V+D[superscript *+] samples with the CDF II detector. The D[superscript *+] is fully reconstructed in the D[superscript *](2010)[superscript +] → D[superscript 0](→K[superscript -]π[superscript +])π[superscript +] 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 σ(W + D[superscript *])/σ(W) = [1.75 ± 0.13(stat) ± 0.09(stat)]% and σ(Z + D[superscript *])/σ(Z) = [1.5 ± 0.4(stat) ± 0.2(stat)]% and perform a differential measurement of dσ(W + D[superscript *])/dp[subscript T](D[superscript *]). Event properties are utilized to determine the fraction of V + D[superscript *](2010)[superscript +] 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.
