Summary

The Lambda+c lifetime was measured using electron-positron collision data. This study provides a precise measurement of the Lambda+c baryon

Area of Science:

  • Particle Physics
  • High Energy Physics
  • Hadron Spectroscopy

Background:

  • The Lambda+c baryon is a charm baryon crucial for understanding weak decays.
  • Precise lifetime measurements of charm baryons test theoretical models of particle physics.

Purpose of the Study:

  • To measure the lifetime of the Lambda+c baryon with high precision.
  • To compare measurements from e+e- annihilation with fixed-target experiments.

Main Methods:

  • Utilized 9.0 fb^-1 of e+e- annihilation data collected by the CLEO II.V detector at CESR.
  • Employed an unbinned maximum likelihood fit to analyze the data.

Main Results:

  • The Lambda+c lifetime is determined to be 179.6 ± 6.9 (stat) ± 4.4 (syst) fs.

  • The precision of this measurement is comparable to existing fixed-target experiments.

    • Conclusions:

    • This measurement contributes to a more accurate understanding of charm baryon properties.
    • The comparable precision highlights the viability of e+e- annihilation for such studies, offering complementary systematic uncertainties.
