Description

The plane-wave quantization condition is a recently proposed alternative to the Lüscher two-particle formalism. It is based on the use of an effective potential to describe particle interactions and makes it possible to incorporate one-particle exchange (OPE) effects in the analysis of lattice results. From the potential, finite-volume energies and infinite-volume scattering amplitudes are obtained from the Lippmann-Schwinger equation in finite and infinite-volume, respectively. The inclusion of OPE effects may play a very important role when describing baryon-baryon scattering results from lattice simulations, especially as the physical pion mass is approached. In this poster, I will summarize the plane-wave quantization condition and present its application to the $H$-dibaryon system and the two-nucleon system. We find that this new quantization condition allows one to capture one-pion exchange effects, which have a non-negligible impact in the results for the scattering amplitude.
