چکیده
We measure the masses of b hadrons in exclusively reconstructed final states containing a J/psi --> mu-mu+ decay using 220 pb(-1) of data collected by the CDF II experiment. We find: m(B+) = 5279.10 +/- 0.41(stat.) +/- 0.36(sys.) MeV/c2, m(B0) = 5279.63 +/- 0.53(stat.) +/- 0.33(sys.) MeV/c2, m(B(s)0) = 5366.01 +/- 0.73(stat.) +/- 0.33(sys.) MeV/c2, m(lambda(b)0) = 5619.7 +/- 1.2(stat.) +/- 1.2(sys.) MeV/c2. m(B+) - m(B0) = -0.53 +/- 0.67(stat.) +/- 0.14(sys.) MeV/c2, m(B(s)0) - m(B0) = 86.38 +/- 0.90(stat.) +/- 0.06(sys.) MeV/c2, m(lambda(b)0) - m(B0) = 339.2 +/- 1.4(stat.) +/- 0.1(sys.) MeV/c2. The measurements of the B(s)0, lambda(b)0 mass, m(B(s)0) - m(B0) and m(lambda(b)0) - m(B0) mass difference are of better precision than the current world averages.

Heavy 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 کاملSemileptonic decays of the bottom-charm hadrons
We present the results of a study of the semileptonic decays of the Bc-meson and the lowest lying doubly heavy baryons using the relativistic quark model. We do not employ a heavy quark mass expansion but keep the masses of the heavy quarks and hadronss finite. We calculate all relevant form factors and decay rates. The semileptonic decays of heavy mesons and baryons are ideally suited to extra...
متن کاملCp Violation, Mixing and Rare Decays at the Tevatron Now and in Run Ii I Introduction
We review the status of current B mixing and CP violation measurements from the Fermilab Tevatron. With the existing data sample, the CDF collaboration has made competitive measurements of B 0 d mixing; set limits on B 0 s mixing; and has begun a direct search for CP violation in the B system through the decay B 0 =B 0 ! J==K 0 s. The prospects for future b measurements at the Tevatron, includi...
متن کاملthe DELPHI detector at LEP.
Study of spectral moments in semileptonic decays of the b hadron with the DELPHI detector at LEP. The measurement of the moments of hadronic mass spectrum and of lepton energy spectrum based on a sample of semileptonic decays of the b hadron selected from Z 0 → b ¯ b events recorded with the Delphi detector at LEP, are presented. These results are interpreted in terms of constraints on the quar...
متن کاملMeasurement of Heavy Quark cross-sections at CDF
The measurement of heavy quark cross-sections provides important tests of the QCD theory. This paper reviews recent measurements of single b-quark and correlated b-quark cross-sections at CDF. Two new measurements of the single b-quark production at CDF agree with the first result from CDF Run II. This clarifies the experimental situation and confirms the recent agreement of theoretical predict...
