Measurement of vector boson plus D∗(2010)+ meson production in p ̄p collisions at √s = 1.96 TeV


CDF Collaboration; et al; Canelli, F; Kilminster, B (2016). Measurement of vector boson plus D∗(2010)+ meson production in p ̄p collisions at √s = 1.96 TeV. Physical review. D:052012.

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 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)+→D0(→K-π+)π+ 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*)/σ(W)=[1.75±0.13(stat)±0.09(stat)]% and σ(Z+D*)/σ(Z)=[1.5±0.4(stat)±0.2(stat)]% and perform a differential measurement of dσ(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.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
