Özet
Based on a sample of (448.1±2.9)×106 ?(3686) events collected with the BESIII detector at BEPCII, the decays of ?(3686)?K-??¯++c.c. with ?¯+??¯?+, ?¯?p¯?+ are studied. We investigate the two excited resonances, ?(1690)- and ?(1820)-, which are each observed with large significance (?10?) in the K-? invariant mass distributions. A partial wave analysis is performed, and the spin-parities of ?(1690)- and ?(1820)- are measured to be 12- and 32-, respectively. The masses, widths, and product branching fractions of ?(1690)- and ?(1820)- are also measured. © 2024 authors. Published by the American Physical Society.
