Based on 6.1 fb^{-1} of e^{+}e^{-} annihilation data collected at center-of-mass energies from 4.600 to 4.843 GeV with the BESIII detector BEPCII collider, a partial wave analysis Λ_{c}^{+}→Λπ^{+}η is performed, and branching fractions decay asymmetry parameters intermediate processes are determined. The process Λ_{c}^{+}→Λa_{0}(980)^{+} observed for first time, evidence pentaquark candidate Σ(1380)^{+} decaying into Λπ^{+} found statistical significance larger than 3σ mass width fixed...

We study the process e^{+}e^{-}→Λ_{c}^{+}Λ[over ¯]_{c}^{-} at twelve center-of-mass energies from 4.6119 to 4.9509 GeV using data samples collected by BESIII detector BEPCII collider. The Born cross sections and effective form factors (|G_{eff}|) are determined with unprecedented precision after combining single double-tag methods based on decay Λ_{c}^{+}→pK^{-}π^{+}. Flat around 4.63 obtained no indication of resonant structure Y(4630), as reported Belle, is found. In addition, oscillatory...
