Abstract:

By using 1.8×106 DD̄ pairs, we have measured B(D0→π-e+νe)=0.299(11)(9)%, B(D+→π0e+νe)=0.373(22)(13)%, B(D0→K-e+νe)=3.56(3)(9)%, and B(D+→K̄0e+νe)=8.53(13)(23)% and have studied the q2 dependence of the form factors. By combining our results with recent lattice calculations, we obtain |Vcd|=0.217(9)(4)(23) and |Vcs|=1.015(10)(11)(106). © 2008 The American Physical Society.

Abstract:

Using a sample of 1.8 million DD̄ mesons collected at the ψ(3770) with the CLEO-c detector, we study the semileptonic decays D0→π-e+νe, D+→π0e+νe, D0→K-e+νe, and D+→K̄0e+νe. For the total branching fractions we find B(D0→π-e+νe)=0.299(11)(9)%, B(D+→π0e+νe)=0.373(22)(13)%, B(D0→K-e+νe)=3.56(3)(9)%, and B(D+→K̄0e+νe)=8.53(13)(23)%, where the first error is statistical and the second systematic. In addition, form factors are studied through fits to the partial branching fractions obtained in five q2 ranges. By combining our results with recent unquenched lattice calculations, we obtain |Vcd|=0.217(9)(4)(23) and |Vcs|=1.015(10)(11)(106), where the final error is theoretical. © 2008 The American Physical Society.

Abstract:

We report on a search for narrow-width particles decaying to a top and antitop quark pair. The data set used in the analysis corresponds to an integrated luminosity of 680pb-1 collected with the Collider Detector at Fermilab in run II. We present 95% confidence level upper limits on the cross section times branching ratio. Assuming a specific top-color-assisted technicolor production model, the leptophobic Z′ with width ΓZ′=0.012MZ′, we exclude the mass range MZ′<725GeV/c2 at the 95% confidence level. © 2008 The American Physical Society.
