本文研究了海夸克电磁荷对介子质量的影响，并首次得到了海夸克电磁荷对介子质量的影响。<?format ?>全低能常数。本文采用重加权方法将海夸克的电磁荷引入到淬火QCD格点模拟中。本文用随机方法估计了连接猝灭和非猝灭QED的重加权因子。
The effect of sea quark electromagnetic charge on meson masses is investigated, and first results for <?format ?>fulllow-energy constants are presented. The electromagnetic charge for sea quarks is incorporated in quenchedQCD lattice simulations by a reweighting method. The reweighting factor, which connects quenched and unquenched QED, is estimated using a stochastic method onflavor dynamical domain-wall quark ensembles.
