title = "Measurements of Absolute Hadronic Branching Fractions of the Λc+ Baryon",
abstract = "We report the first measurement of absolute hadronic branching fractions of Λc+ baryon at the Λc+Λ¯c- production threshold, in the 30 years since the Λc+ discovery. In total, 12 Cabibbo-favored Λc+ hadronic decay modes are analyzed with a double-tag technique, based on a sample of 567 pb-1 of e+e- collisions at s=4.599 GeV recorded with the BESIII detector. A global least-squares fitter is utilized to improve the measured precision. Among the measurements for twelve Λc+ decay modes, the branching fraction for Λc+→pK-π+ is determined to be (5.84±0.27±0.23)%, where the first uncertainty is statistical and the second is systematic. In addition, the measurements of the branching fractions of the other 11 Cabibbo-favored hadronic decay modes are significantly improved.",
