Measurement of the c+ lifetime Academic Article uri icon

abstract

  • The c+ lifetime is measured using 9.0 fb-1 of e+e- annihilation data collected on and just below the (4S) resonance with the CLEO II.V detector at CESR. This is the first measurement of the c+ lifetime from a collider experiment. Using an unbinned maximum likelihood fit, the c+ lifetime is measured to be 503 47(stat) 18(syst) fs. The precision of this measurement is comparable to previous measurements carried out by fixed target experiments with different sources of systematic uncertainties.
