DESCRIPTION:Speakers: Tyler Blanton (*) (University of Washington)\nWe pre
sent a simplified derivation of the relativistic three-particle quantizati
on condition for identical\, spinless particles. The simplification is aff
orded by using time-ordered perturbation theory (TOPT) and a three-particl
e quasilocal K matrix that is not fully symmetrized to organize the releva
nt diagrams in an intuitive manner\, ultimately leading to a new form of t
he quantization condition. This form can then be related algebraically to
both the standard quantization condition\, which uses a fully symmetric th
ree-particle K matrix\, and the quantization condition based on extending
unitary representations of the three-particle amplitude to finite volume.
It should also allow a more straightforward generalization of the quantiza
tion condition to nondegenerate particles\, and perhaps also to more than
three particles.\n\nhttps://conference-indico.kek.jp/event/113/contributio
