Two- and three-particle scattering in the (1+1)-dimensional O(3) non-linear sigma model
Jorge Baeza-Ballesteros, Maxwell T. Hansen
We study two- and three-particle scattering in the O(3) non-linear sigma model in 1+1 dimensions, focusing on the isospin-1 and isospin-2 channels for two particles, and the isospi…

A lattice study of scattering at large
Jorge Baeza-Ballesteros, Pilar Hernández, Fernando Romero-López
We present the first lattice study of pion-pion scattering with varying number of colors, . We use lattice simulations with four degenerate quark flavors, $N_\text{f}=4…
