Abstract: We develop an extension of the No-Core Shell Model (NCSM) to hypernuclei. We outline the formalism of the NCSM and the computational methods needed to solve the quantum many-body problem. A major computational challenge is the rapid growth of the model space with the number of particles in the system and the model-space truncation parameter. We mitigate this by introducing an importance-truncation scheme that restricts the model space to the parts that are deemed important for the problem at hand. Also, to speed up convergence with the model-space truncation, we perform a Similarity Renormalisation Group transformation on the Hamiltonian before the calculation. We close with example calculations of two p-shell hypernuclei and discuss the implications of our results on the construction of hyperon-nucleon interactions as well as on neutron-star physics.
