Measurement of the Bs meson lifetime. Academic Article uri icon

abstract

  • The lifetime of the Bs meson is measured using the semileptonic decay BsDs-+X. The data sample consists of 19.3 pb-1 of pp collisions at s=1.8 TeV collected by the Collider Detector at Fermilab during 1992-1993. There are 768 +Ds- signal events where the Ds is identified via the decay Ds--, K+K-. Using these events, the Bs meson lifetime is determined to be s=1.42-0.23+0.27(stat)0.11(syst) ps. A measurement of the Bs lifetime in a low statistics sample of exclusive BsJ/ decays is also presented in this paper. 1995 The American Physical Society.
