标题： Aharonov-Bohm effect and nucleon-nucleon phase shifts on the lattice

摘要： 我们提出一种用于核子-核子低能相互作用的格点QCD计算方法。 它包括在背景的“电磁”场中模拟QCD，该场的势不为零，但场强为零。 通过调节背景场，可以通过测量基态能量的偏移来确定任意（但较小）动量的相移。 对于计算到动量约为$m_{\pi}/2$的相移，5费米的格点大小可能已经足够。 显示英文摘要

摘要： We propose a method for the lattice QCD computation of nucleon-nucleon low-energy interactions. It consists in simulating QCD in the background of a ''electromagnetic" field whose potential is non-vanishing, but whose field strength is zero. By tuning the background field, phase-shifts at any (but small) momenta can be determined by measuring the shift of the ground state energy. Lattice sizes as small as 5 Fermi can be sufficient for the calculation of phase shifts up to momenta of order of $m_{\pi}/2$.
