论文摘要
使用动力学晶格量子染色体动力学(QCD+QED)计算和有效的现场理论,研究了具有多达十二个带电和中性伪级膜的量子数的系统,以及中性和中性的伪级膜以及一,二和三核系统。 QED对HADRONIC相互作用的影响是通过比较夸克质量来消除强大的同胞断裂效应后比较带电和中性哈子的系统来确定的。分析了多个带电的HADRON的系统,并发现一种非相关的有效野外理论,该理论在扰动上包括有限体积库仑效应,并发现可以准确地重现晶格QCD+QED结果。 QED对库仑光子交换以外的带电的多 - 二龙系统的影响是通过比较从晶格QCD+QED结果中提取的两体和三体相互作用参数来确定的。
Systems with the quantum numbers of up to twelve charged and neutral pseudoscalar mesons, as well as one-, two-, and three-nucleon systems, are studied using dynamical lattice quantum chromodynamics and quantum electrodynamics (QCD+QED) calculations and effective field theory. QED effects on hadronic interactions are determined by comparing systems of charged and neutral hadrons after tuning the quark masses to remove strong isospin breaking effects. A non-relativistic effective field theory, which perturbatively includes finite-volume Coulomb effects, is analyzed for systems of multiple charged hadrons and found to accurately reproduce the lattice QCD+QED results. QED effects on charged multi-hadron systems beyond Coulomb photon exchange are determined by comparing the two- and three-body interaction parameters extracted from the lattice QCD+QED results for charged and neutral multi-hadron systems.
