Phys. Rev. D 25, 3073–3074 (1982)Current algebra, ππ scattering lengths, and the S*(980) background contributionReceived 11 January 1982; published in the issue dated 1 June 1982 We demonstrate that the recently measured S*(980)→ππ decay width implies an S* background contribution in addition to the Weinberg low-energy ππ amplitude which significantly improves the agreement between the current-algebra theory for ππ scattering lengths and experiment. © 1982 The American Physical Society URL:
