Description
I will show how nuclear structure can be predicted from lattice QCD through low-energy effective field theories (EFTs), using as an example simulations of a world with relatively heavy quarks. At distances scales much larger than the inverse pion mass few-nucleon systems are described by an EFT where the leading interactions are contact two- and three-body forces, which explicitly incorporate the universality of weakly bound systems. After matching to the results of lattice simulations for few-nucleon systems, the solution of the EFT with ab initio methods, such as effective-interaction hyperspherical harmonics and auxiliary-field diffusion Monte Carlo, allows the calculation of properties of larger systems.
