摘要：
We point out that the finite-size behaviour of hadron masses is described well with a power law, rather than with an exponential form predicted by an analytic formula derived from a field theory treatment for point particles. It is also argued that the finite-size effect arises dominantly from a real size of hadrons squeezed on a finite lattice. Possible explanations are suggested for the origin of the power law.
