Title: Studies of the B(c) meson at CDF

Abstract

The authors present the latest measurements of the B{sub c} meson properties using 360 pb{sup -1} of data collected by the CDF detector. The results include the B{sub c} mass and the ratio of branching fraction B{sub c} {yields} J/{psi} l with respect to B {yields} J/{psi}K.

  • We present results on charmonium production, b quark and B meson production and B{bar B} correlations using data taken with the CDF detector at Fermilab in p{bar p} collisions at {radical}s = 1.8 TeV during the 1992--1993 collider run.
  • The authors present recent CDF measurements of {tau}{sup +}, {tau}{sup 0}, and {tau}{sup +}/{tau}{sup 0} using exclusive B {yields} {psi}K decays, where B = B{sup +} or B{sup 0}, {psi} = J/{psi} or {psi}(2S), and K = K{sup +}, K*(892){sup 0}, K{sub S}{sup 0}, or K*(892){sup +}. The precision of these results is less than 10% and is nearly identical to that previously reported at LEP.
  • We present a search for the {ital B}{sup +}{sub {ital c}}{yields}{ital J}/{Psi}{pi}{sup {+-}}. We measure the limit of {delta}({ital B}{sup {+-}}{sub {ital c}}){center_dot}{ital BR(B{sub c}{sup {+-}}{yields}J/{Psi}{pi}{sup {+-}})/{delta}(B{sup +-}{sub u}){center_dot}BR(B{sup {+-}}{sub u}{yields}J/{Psi}{Kappa}{sup {+-}}}) as a function of the {ital B{sup {+-}}{sub c}} lifetime, using {approx} 110 {ital pb}{sup -1} of data collected at the Collider Detector at Fermilab (CDF). We present also a search for the rare decays {ital B}{sup 0}{sub {ital d}}{yields}{mu}{sup +}{mu}{sup -} and {ital B}{sup 0}{sub {ital s}}{yields}{mu}{sup +}{mu}{sup -}, setting an upper limit on their respective branching ratios.
  • The high rate of B{anti B} production at the Tevatron makes it a unique place for the study of B production and decay. Although e{sup +}e{sup {minus}} colliders provide a cleaner environment than hadron colliders for the study of B decays, CDF has shown that exclusive B channels can be successfully reconstructed in a harsh environment. Their data have been taken in p{anti p} collisions at {radical}s = 1.8 TeV with the CDF detector during the 1988--89 and the 1992--93 collider runs. The CDF detector has been upgraded before the start of the 1992--93 run. The authors have collected {approximately}21more » pb{sup {minus}1} of data with this upgraded detector during the 1992--93 run. During the 1988--89 collider run CDF has shown that once can study quarkonia physics and b physics even in a harsh p{anti p} collider environment. The data collected with the upgraded CDF detector during the 1992--93 run are leading them to a rich program which focuses on the production and decay of quarkonia and b-quarks, and which will answer many of the questions posed during the 1988--89 collider run. Results from both runs are concluded.« less
