Title: Observation of the {ital B}{sub {ital c}} Meson in {ital p}{ovr {ital p}} Collisions at {radical} ({ital s}) =1.8 TeV

Abstract

We have observed bottom-charm mesons via the decay mode B{sup {plus_minus}}{sub c}{r_arrow}J/{psi}thinsp {ell}{sup {plus_minus}}{nu} in 1.8thinspthinspTeV p{ovr p} collisions using the CDF detector at the Fermilab Tevatron. A fit of background and signal contributions to the J/{psi}thinsp{ell} mass distribution yielded 20.4{sup +6.2}{sub {minus}5.5} events from B{sub c} mesons. A fit to the same distribution with background alone was rejected at the level of 4.8thinspthinspstandard deviations. We measured the B{sup +}{sub c} mass to be 6.40{plus_minus}0.39(stat){plus_minus}0.13( syst) GeV/c{sup 2} and the B{sup +}{sub c} lifetime to be 0.46{sup +0.18}{sub {minus}0.16}(stat) {plus_minus}0.03(syst)thinspps . Our measured yield (production cross section times branching ratio) for B{sup +}{sub c}{r_arrow}J/{psi}thinsp{ell}{sup +}{nu} relative to that for B{sup +}{r_arrow}J/{psi}thinspK{sup +} is 0.132{sup +0.041}{sub {minus}0.037}(stat ){plus_minus}0.031(syst){sup +0.032}{sub {minus}0.020}(lifetime) . {copyright} {ital 1998} {ital The American Physical Society }
