标题： Finite size mass shift formula for stable particles revisited

摘要： 卢舍尔在周期性有限体积中的有限尺寸质量位移公式，重新考虑了涉及无限体积中正向散射振幅的两个稳定可区分粒子系统。 分别在玻色子-玻色子和费米子-玻色子系统中推导了玻色子和费米子的广义质量位移公式。 讨论了核子-介子系统中的核子质量位移。 显示英文摘要

摘要： Luescher's finite size mass shift formula in a periodic finite volume, involving forward scattering amplitudes in the infinite volume, is revisited for the two stable distinguishable particle system. The generalized mass shift formulae for the boson and fermion are derived in the boson-boson and fermion-boson systems, respectively. The nucleon mass shift is discussed in the nucleon-pion system.
