DESCRIPTION:Speakers: Stephen R. Sharpe\, Tyler Blanton (*) (University of
Washington)\n\nWe present a simplified derivation of the relativistic thr
ee-particle quantization condition for identical\, spinless particles. The
simplification is afforded by using time-ordered perturbation theory (TOP
T) and a three-particle quasilocal K matrix that is not fully symmetrized
to organize the relevant diagrams in an intuitive manner\, ultimately lead
ing to a new form of the quantization condition. This form can then be rel
ated algebraically to both the standard quantization condition\, which use
s a fully symmetric three-particle K matrix\, and the quantization conditi
on based on extending unitary representations of the three-particle amplit
ude to finite volume. It should also allow a more straightforward generali
zation of the quantization condition to nondegenerate particles\, and perh
aps also to more than three particles.\n\nhttps://conference-indico.kek.jp
