DESCRIPTION:Speakers: 浩飞 高 (SJTU)\nHeavy-meson light-cone distributi
 on amplitudes are essential nonperturbative inputs for precision heavy-fla
 vor phenomenology. We present a first-principles lattice-QCD determination
  of heavy-meson LCDAs in both QCD and HQET using the HQLaMET framework. Si
 mulations on multiple ensembles enable controlled continuum\, chiral\, and
  infinite-momentum extrapolations. Improved lattice techniques significant
 ly enhance the quality of nonlocal correlators. For the HQET LCDA\, we com
 bine the nonperturbative peak region with the perturbative tail and determ
 ine key inverse moments\, obtaining (\\lambda_B = 0.340(20)) GeV at (\\mu 
 = 1) GeV.\n\nhttps://indico.itp.ac.cn/event/437/contributions/2854/
