Abstract: Even though it has been half a century since Quantum Chromodynamics (QCD) has been identified as the fundamental theory of the strong interactions,  the non-perturbative nature of QCD has placed large restriction on the physical phenomena that can be directly obtained from the theory. Lattice QCD, being a non-perturbative framework, provides a promising pathway towards studying QCD eigenstates and their dynamics. Being defined in a finite-Euclidean spacetime, the notion of scattering is absent within lattice QCD. Despite this obstacle, one can find exact relations between the finite-volume observables constrained via lattice QCD and desired scattering amplitudes in an infinite-Minkowski spacetime. In this talk, I introduce some of the basic concepts that have opened up this line of research, I give some examples of this being put into practice, and I discuss some related open problems.  

Raúl Briceño was born and raised in Caracas, Venezuela. In 2013, he received his PhD in Physics from the University of Washington. His research largely focuses on non-perturbative aspects of few-body systems in nuclear, particle, and even some atomic physics. In 2023, he joined the Physics Department with a joint affiliation in the Nuclear Theory group at Lawrence Berkeley National Lab.
