标题： Lattice QCD Constraints on the Fourth Mellin Moment of the Pion Light Cone Distribution Amplitude using the HOPE method

摘要： π轻锥分布振幅（LCDA）包含了由夸克携带的部分子动量的信息，在高能下各种非弹性过程的诸多预测中是一个重要的理论输入，包括π电磁形式因子。文中介绍了利用重夸克算符乘积展开（HOPE）方法限制LCDA的第四个Mellin矩进展。 显示英文摘要

摘要： The light-cone distribution amplitude (LCDA) of the pion contains information about the parton momentum carried by the quarks and is an important theoretical input for various predictions of exclusive processes at high energy, including the pion electromagnetic form factor. Progress towards constraining the fourth Mellin moment of the LCDA using the heavy-quark operator product expansion (HOPE) method is presented.
