DESCRIPTION:Speakers: Jin Sun\n\n In this talk\, I will introduce arXiv:25
 09.22087 (Published in PRL on 4 Feb\,2026)\, where the authors develop a p
 QCD factorization framework for the high-energy Λ hyperon EDM form factor
  measured in (J /\\ psi --> Λ \\bar{Λ} ). \nThe central observation is t
 hat BESIII constrains the time-like form factor (dΛ(Q=M_{J /\\ psi}))\, r
 ather than the static EDM (dΛ(0)). By matching quark EDM and chromo-EDM 
 operators onto hard kernels convoluted with Λ twist-3 LCDAs\, the authors
  show that the Λ EDM provides a direct and complementary probe of the str
 ange-quark chromo-EDM.\n\nhttps://indico.ibs.re.kr/event/1320/
