Description
The strong nuclear force is the residual interaction between hadrons, which are bound states of quarks and gluons. These fundamental particles interact via Quantum Chromodynamics (QCD), a strongly-coupled non-abelian gauge theory, which must be simulated on a discrete space-time lattice using high-performance computing resources. Such simulations are necessarily performed in `imaginary' time, so that Monte Carlo importance sampling may be applied. While certain properties like energies and matrix elements are independent of the time signature, determining real-time scattering amplitudes from imaginary-time simulations is a challenge. Nonetheless, I will discuss recent results and future prospects for hadron scattering amplitudes from lattice QCD simulations.
