Abstract:

In this paper we report a measurement of the tt̄ production cross section in pp̄ collisions at √s=1.96TeV using data corresponding to an integrated luminosity of 2.2fb-1 collected with the CDF II detector at the Tevatron accelerator. We select events with significant missing transverse energy and high jet multiplicity. This measurement vetoes the presence of explicitly identified electrons and muons, thus enhancing the tau contribution of tt̄ decays. Signal events are discriminated from the background using a neural network, and heavy flavor jets are identified by a secondary-vertex tagging algorithm. We measure a tt̄ production cross section of 7.99±0.55(stat)±0.76(syst)±0.46(lumi) pb, assuming a top mass mtop=172.5GeV/c2, in agreement with previous measurements and standard model predictions. © 2011 American Physical Society.

Abstract:

We report the first observation of the decay D+→η ′e+νe in two analyses, which combined provide a branching fraction of B(D+→η ′e+νe)=(2.16±0.53±0.07) ×10-4. We also provide an improved measurement of B(D +→ηe+νe)=(11.4±0.9±0. 4)×10-4, provide the first form factor measurement, and set the improved upper limit B(D+→e+νe)<0. 9×10-4 (90%C.L.). © 2011 American Physical Society.
