Measurement of vector boson plus D*(2010)+ meson production in ¯pp collisions at vs=1.96?TeV

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 vs=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)+?D0(?K-p+)p+ 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 s(W+D*)/s(W)=[1.75±0.13(stat)±0.09(stat)]% and s(Z+D*)/s(Z)=[1.5±0.4(stat)±0.2(stat)]% and perform a differential measurement of ds(W+D*)/dpT(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.
