Description

Real-Time Estimators for Scattering Observables (RESOs) is a proposal for the extraction of scattering amplitudes from simulations on quantum computers. Unlike the Lüscher family of methods on traditional Lattice QCD, RESOs shows that access to real-time correlators, increasingly achievable through quantum hardware, permits the study of general reactions without formal roadblocks associated to the energies involved. In order to show this, in 2506.06511 we explored the finite-volume effects of generic scattering processes in perturbation theory. In this talk we will show how the Feynman epsilon prescription suppresses finite-volume effects, and we will further show how we can enhance this suppression through a restoration of Lorentz invariance by averaging results in multiple frames.
