Studies of the B C Meson at Cdf
We present the latest measurements of the Bc meson properties using 360 pb −1 of data collected by the CDF detector. The results include the Bc mass and the ratio of branching fraction Bc → J/ψ l with respect to B → J/ψK.
متن کاملHeavy quark meson spectroscopy at CDF
With growing datasets collected by the CDF II experiment, studies of the spectroscopy of mesons containing heavy quarks become more exciting. The CDF experiment has good capabilities in both charm and bottom sector. This capability allowed also to contribute to the study of the zoo of states called X,Y, Z. In this area we present a recent update of the mass measurement of X(3872). The result m(...
متن کاملB 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 .
متن کاملUnderlying Event Studies at Cdf
We present recent studies about the 'underlying event' which originates mostly from soft spectator interactions. First Run II data results are compared to published Run I results and to QCD Monte Carlo models.
متن کاملD Meson Decay Studies at the V
The status of our understanding of the weak decay mechanism for charmed mesons is discussed in the light of new, preliminary results from the Mark III at SPEAR, taken at the YF’ resonance. Branching ratios for several previously unobserved Cabibboallowed and suppressed decay modes of D+ and D' are presented. A new analysis of the Dalitr plots of decays to pseudoscalar vector channels is discuss...
