Bsmixing andBhadron lifetimes at CDF

Measurements of B hadron lifetimes at CDF

Using data samples in excess of 1 fb collected by the CDF II detector we present several world’s best measurements of B hadron lifetimes. They include Bs meson lifetime in a flavor-specific decay mode, combining fully and partially reconstructed hadronic decays, B c meson lifetimes in semileptonic B + c → J/ψl X, l = μ, e decays and Λb baryon lifetime in Λ+c π − fully-reconstructed decays. In a...

/ and Jets at Cdf

Events with signatures involving large missing transverse energy (E T /) are among the quintessential search modes for R-parity conserving supersymmetry. CDF has conducted two recent analyses for supersymmetry which use E T / and jets. The E T / and monojet signature is employed to determine process independent limits for the production of new physics beyond the Standard Model and then applied ...

Hard diffraction at CDF

We present a CDF measurement of diffractive dijet production in p̄p collisions at 1.96 TeV at the Fermilab Tevatron Collider using data from an integrated luminosity of ≈ 310 pb collected by triggering on a high transverse momentum jet in coincidence with a recoil antiproton detected in a roman pot spectrometer. We report final results for 4-momentum transfer squared t > −4 GeV, antiproton-momen...

Beautiful Physics at Cdf

B-physics with pp collisions at CDF is reviewed, including production cross sections, masses, and decay properties. with a focus on lifetime and mixing measurements. A two-component lifetime t of B 0 s ! ` + D ? s X results in the limit ? s =? s < 0:81 (95% C.L.), which is converted into an indirect upper bound on m s. From our ve B 0 d-B 0 d oscillation analyses, we highlight the use of \same ...
