在利用晶格QCD模拟计算虚光子对强子性质的修正的基础上，利用QED的低能量有效理论研究了有限尺寸尺度对QED修正的影响。为此，我们首先在有限体积空间上构造一个新的QED。将此公式应用于部分淬灭的电磁QCD，计算了伪nambu - goldstone玻色子质量电磁修正的有限尺寸尺度效应，并观察了定性特征。
On account of the computation of the virtual photon corrections to the hadronic properties by means of lattice QCD simulation, we study the finite size scaling effect on the QED correction using low energy effective theory of QCD with QED. For this purpose, we begin with formulating a new QED on the space with finite volume. By adapting this formalism to the partially quenched QCD with electromagnetism, we compute the finite size scaling effect on the electromagnetic correction to the masses of pseudo-Nambu-Goldstone bosons and observe qualitative features.
