Towards nuclear reactions from lattice QCD

"In this talk I will motivate the evaluation of nuclear reactions cross sections from Lattice Quantum Chromodynamics (LQCD) and discuss challenges associated with such calculations. In particular, I will explore the connection between the energy spectrum of a three-body system in a finite volume and infinite volume scattering matrix elements using an effective field theoretical approach. The implication of this formalism for studying systems composed of a particle and a bound-state below the bound-state break-up will be discussed. I will briefly discuss the similarities of the three-body problem and that of two-body coupled-channels systems and will comment on extensions of the formalism above the break-up threshold."
