DESCRIPTION:Speakers: Xudong Yu (Peking University)\n\nCharm hadrons offer
  a sensitive window into non-perturbative QCD\, connecting weak decays and
  hadron spectroscopy in clean e+e− collisions with heavy-flavor producti
 on and hadronization in nuclear matter. In this seminar\, I will present m
 y work exploring charm hadronic physics from BESIII to sPHENIX. At BESIII\
 , I will focus on studies of charmed-baryon decays\, including the partial
  wave analysis of Λc+→Λπ+η and the first observation of Λc+→nπ+
 η. These analyses probe decay dynamics\, intermediate hadronic structures
 \, and final-state interactions through amplitude modeling\, statistical f
 itting\, and machine-learning techniques developed to improve sensitivity 
 in challenging backgrounds. I will also briefly discuss the J/ψ energy co
 rrelator as a new observable related to charmonium hadronization. Building
  on these interests\, I will then discuss my work at sPHENIX\, where charm
  hadrons are studied in the more complex environment of high-energy nuclea
 r collisions. I will highlight my contributions to tracking calibration\, 
 online analysis\, and light- and heavy-flavor reconstruction\, which are e
 ssential steps toward precision measurements of charm production and hadro
 nization in the QCD medium.---------------------\nZoom: https://bnl.zoomgo
