B0s mixing at CDF

Time Dependent B 0 ¯ B 0 Mixing at CDF

Measurements of the frequencies for Bd and Bs mesons to oscillate into B̄d and B̄s, respectively, can potentially constrain the magnitudes of the CKM matrix elements Vts and Vtd. These frequencies are proportional to ∆md and ∆ms, the mass differences between the CP eigenstates of the Bd and Bs mesons. Recent measurements have provided precise determinations of ∆md and lower limits on ∆ms . The la...

B Meson Mixing at Cdf Ii M. Rescigno (for the Cdf Collaboration)

We present the first limit on B 0 s mixing frequency obtained using 360 pb −1 of Tevatron Run II data with the CDF II detector. We derive ∆ms > 7.9 ps −1 @ 95% C.L. with a sensitivity of 8.4ps −1 .

/ 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...
