M. Beneke, Y. Kiyo, K. Schuller

摘要:

计算了S波夸克偶素波函数的三阶修正|中文(简体)|^2在有效非相对论性拉格朗日量的非库仑势的原点。与以前的结果库仑校正和超软校正计算的同伴纸,这完成了三阶计算到几个未知的匹配系数。对bottomonium和toponium给出了新修正的数值估计。

英文摘要:

We compute the third-order correction to the S-wave quarkonium wave functions |ψ_n(0)|^2 at the origin from non-Coulomb potentials in the effective non-relativistic Lagrangian. Together with previous results on the Coulomb correction and the ultrasoft correction computed in a companion paper, this completes the third-order calculation up to a few unknown matching coefficients. Numerical estimates of the new correction for bottomonium and toponium are given.
