在等时相对论量子力学的背景下，引入了洛伦兹增强的双核子势。增强核子-核子势的动力学输入是基于真实的核子势，通过适当的动量标度，它被转换成属于相对论双核子薛定谔方程的核子势。系统。由此得到的洛伦兹增强势与先前介绍的增强型二体t矩阵是一致的。将其应用于三核子束缚态的相对论Faddeev方程中，计算了束缚能。像以前的计算一样，两体子系统的助推效应是排斥的，并降低了结合能。
A Lorentz boosted two-nucleon potential is introduced in the context of equal time relativistic quantum mechanics. The dynamical input for the boosted nucleon-nucleon $(\mathrm{NN})$ potential is based on realistic $\mathrm{NN}$ potentials, which by a suitable scaling of the momenta are transformed into $\mathrm{NN}$ potentials belonging to a relativistic two-nucleon Schr\"odinger equation in the c.m. system. This resulting Lorentz boosted potential is consistent with a previously introduced boosted two-body t matrix. It is applied in relativistic Faddeev equations for the three-nucleon bound state to calculate the ${}^{3}\mathrm{H}$ binding energy. Like in previous calculations the boost effects for the two-body subsystems are repulsive and lower the binding energy.
