Description:
Author(s): Johann Haidenbauer, Christoph Hanhart, Xian-Wei Kang, and Ulf-G. Meißner We analyze the origin of the structures observed in the reactions e + e − → 3 ( π + π − ) , 2 ( π + π − π 0 ) , ω π + π − π 0 , and e + e − → 2 ( π + π − ) π 0 around the antiproton-proton ( p ¯ p ) threshold. We estimate the contribution of the two-step process e + e − → N ¯ N → multipions to the total reaction amplitude. The amplitude for e + e − → N ¯ N i… [Phys. Rev.
