评“重夸克质量的格点量子色动力学中两个核子是否束缚?”- 用Lüscher的有限体积公式进行健全性检查-”
Comment on "Are two nucleons bound in lattice QCD for heavy quark masses? - Sanity check with Lüscher's finite volume formula -"
摘要:
在这篇评论中,我们解决了HALQCD合作最近预印本中提出的一些错误讨论和结论,arXiv:1703.07210。特别是,我们证明,格点量子色动力学确定的夸克质量对应的介子质量为$m_π= 806$兆电子伏的束缚态是强大的,和NPLQCD合作为这些系统提取的相移通过所有的“健全检查”中介绍的arXiv:1703.07210。
英文摘要:
In this comment, we address a number of erroneous discussions and conclusions presented in a recent preprint by the HALQCD collaboration, arXiv:1703.07210. In particular, we demonstrate that lattice QCD determinations of bound states at quark masses corresponding to a pion mass of $m_π= 806$ MeV are robust, and that the phases shifts extracted by the NPLQCD collaboration for these systems pass all of the 'sanity checks' introduced in arXiv:1703.07210.
