Goal of the present research project is to reach a better control of quarkonium production processes at high energy colliders by using effective field theory methods, lower energy factorizations, developing new tools for automatic calculation of perturbative matching coefficients, devising novel methods for the numerical computations of low energy nonperturbative matrix elements and correlators, once that an appropriate calculational scheme has been obtained. The same technology will be applied to the study of Higgs decay to quarkonium at LHC that can serve as a tool of investigation for the Higgs coupling to heavy quarks.

本研究的目标是通过有效场论方法、低能因子分解、微扰匹配系数自动计算新工具、低能非微扰矩阵数值计算新方法，实现对高能对撞机上夸克偶素产生过程的更好控制 元件 和 电冰箱，一旦 的 一个 得到了合适的计算方案。同样的技术将被应用于研究希格斯衰变到夸克偶素在大型强子对撞机，可以作为一种工具的调查希格斯耦合到重夸克。
