摘要:

本文简要地回顾了最近提出的一种构造相互作用双费米子系统电磁流四维矩阵元精确三维约化的方法。所获得的三维电流的属性,如履行沃德-高的身份和福克分解,将说明与未来的应用程序,以少核子系统。

英文摘要:

A recent approach for constructing an exact 3D reduction of the 4D matrix elements of the electromagnetic current for an interacting two-fermion system, is briefly reviewed. The properties of the obtained 3D current, like the fulfillment of the Ward-Takashi Identity and its Fock decomposition, will be illustrated in relation with future applications to few-nucleon systems.
