The nuclear shell model is a powerful tool to investigate medium-mass regions of the nuclear chart. Its main ingredient is an effective valence-space Hamiltonian. This Hamiltonian consists of single-particle energies, two-body matrix elements and additional many-body contributions. We construct a family of effective Hamiltonians in the sd-shell. The considered interactions are motivated by chiral effective field theory. Thus they incorporate basic QCD symmetry principles by default, allow to study an order-by-order convergence behavior, and come with a theoretically motivated error estimate for missing higher-order contributions.
