The Λc+ baryon mass is measured using Λc+→ΛKS0K+ and Λc+→Σ0KS0K+ decays reconstructed in 232 fb-1 of data collected with the BABAR detector at the PEP-II asymmetric-energy e+e- storage ring. The Λc+ mass is measured to be 2286.46±0.14 MeV/c2. The dominant systematic uncertainties arise from the amount of material in the tracking volume and from the magnetic field strength.

Abstract
The Λc+ baryon mass is measured using Λc+→ΛKS0K+ and Λc+→Σ0KS0K+ decays reconstructed in 232 fb-1 of data collected with the BABAR detector at the PEP-II asymmetric-energy e+e- storage ring. The Λc+ mass is measured to be 2286.46±0.14 MeV/c2. The dominant systematic uncertainties arise from the amount of material in the tracking volume and from the magnetic field strength.File in questo prodotto:
