英文摘要	The phi(4) double-well theory admits a kink solution, whose rich phenomenology is strongly affected by the existence of a single bound excitation called the shape mode. We find that the leading quantum correction to the energy needed to excite the shape mode is -0.115567 lambda/M in terms of the coupling lambda/4 and the meson mass M evaluated at the minimum of the potential. On the other hand, the correction to the continuum threshold is -0.433 lambda/M. A naive extrapolation to finite coupling then suggests that the shape mode melts into the continuum at the modest coupling of lambda/4 similar to 0.106M(2), where the Z(2) symmetry is still broken.
