Description
In 2210.08051, Briceño, Jackura, Rodas and Guerrero developed formalism allowing us to explore the process gamma gamma -> pi pi through lattice results. Such a process is of importance to, for example, our understanding of glueballs and muon g-2. It is also a stepping stone towards beyond standard model physics, such as double beta decay. We will explain ongoing work towards testing this formalism in a 1+1D calculation of the analogous reaction in the O(3) nonlinear sigma model. In particular, we will present preliminary results of the determination of the low-lying spectrum of the theory and the spatial one particle form factors.
