Measurement of the ratio of branching fractions B(D0→K+π-)/ B(D0→K-π+) using the CDF II detector
Physical Review D - Particles, Fields, Gravitation and Cosmology 74:3 (2006)
Abstract:
We present a measurement of RB, the ratio of the branching fraction for the rare decay D0→K+π- to that for the Cabibbo-favored decay D0→K-π+. Charge-conjugate decays are implicitly included. A signal of 2005±104 events for the decay D0→K+π- is obtained using the CDF II detector at the Fermilab Tevatron collider. The data set corresponds to an integrated luminosity of 0.35fb-1 produced in p̄p collisions at s=1.96TeV. Assuming no mixing, we find RB=[4.05±0.21(stat)±0.11(syst)] ×10-3. This measurement is consistent with the world average, and comparable in accuracy with the best measurements from other experiments. © 2006 The American Physical Society.Top quark mass measurement from dilepton events at CDF II with the matrix-element method

Abstract:
We describe a measurement of the top quark mass using events with two charged leptons collected by the CDF II detector from pp̄ collisions with s=1.96TeV at the Fermilab Tevatron. The likelihood in top quark mass is calculated for each event by convoluting the leading order matrix element describing qq̄→tt̄→blνlb̄l′νl′ with detector resolution functions. The presence of background events in the data sample is modeled using similar calculations involving the matrix elements for major background processes. In a data sample with integrated luminosity of 340pb-1, we observe 33 candidate events and measure Mtop=165.2±6.1(stat.) ±3.4(syst.)GeV/c2. This measurement represents the first application of this method to events with two charged leptons and is the most precise single measurement of the top quark mass in this channel. © 2006 The American Physical Society.Model independent measurement of form factors in the decay D+→K-π+e+νe
