Description
I describe recent advances in the development and application of the three-particle formalism that connects the finite-volume spectrum of three (and two) particles to infinite volume three- (and two-) particle scattering amplitudes. Specifically, I will present results from applying this formalism to systems of three pions and/or kaons at maximal isospin at near physical quark masses (work with Sebastian Dawid, Zack Draper, Andrew Hanlon, Ben Horz, Colin Morningstar, Fernando Romero-Lopez, and Sarah Skinner), and will present the generalization of the formalism needed in the presence of multiple three particle channels, focusing on pi+pi+eta and K+Kbar+pi (work with Zack Draper).
