Description
Last year, we presented a generalization of Luescher's two-particle
quantization condition to three identical, degenerate particles.
While completing this work, we discovered a technical problem with our
derivation which invalidated the result, in the sense that not all
finite-volume corrections that fall as powers of the box size were
controlled. We have found
a fix to this problem, which maintains the form of our original result,
but involves a new infinite-volume quantity that is
not directly related to the three-particle scattering amplitude.
We will sketch the problem and its resolution,
and discuss the practical utility of our result.
