英文摘要: With an effective Lagrangian approach, we analyze the K- p -> pi(0)Sigma(0) reaction to study the Lambda hyperon resonances by fitting the Crystal Ball data on differential cross sections and Sigma(0) polarization with the center-of-mass energies of 1536-1676 MeV. Besides well-established Particle Data Group (PDG) four-star Lambda resonances around this energy range, the Lambda(1600)1/2(+) resonance, listed as a three-star resonance in the PDG data, is found to be definitely needed. In addition, there is strong evidence for the existence of a new Lambda(3/2(+)) resonance around 1680 MeV.
