| 英文摘要 | At one loop, quantum kinks are described by a free theory. The nonlinearity and so the interesting phenomenology arrives at two loops, where, for example, internal excitations couple to continuum excitations. We calculate the two-loop mass of a scalar kink. Unlike previous calculations, we include a counterterm which cancels the vacuum energy density at this order, so that our result for the kink mass is finite even when the vacuum energy density is nonzero. This allows us to apply our result to the phi(4) kink, for which we obtain a two-loop mass contribution of 0.0126 lambda/m in terms of the coupling lambda and the meson mass m evaluated at the minimum of the potential.
