Abstract

To gain insight into the universe, spanning from physics Beyond the Standard Model to the understanding of cosmic phenomena and cataclysmic events shaping our world, a unified approach to nuclear structure and reaction mechanisms—extending beyond the elastic threshold—is crucial. This necessitates the integration of few-body techniques with ab initio many-body calculations for the internal structure of the nucleus, all underpinned by an uncertainty quantification scheme facilitated by Effective Field Theory. In this presentation, I will provide an overview of the No-Core Shell Model with Continuum method (NCSMC), highlighting its key components and potential extensions to heavier systems. I will demonstrate how NCSMC empowers us to compute reactions involved in primordial nucleosynthesis from fundamental principles. This talk will offer a concise outline of the formalism, accompanied by selected applications focused on computing nuclear reactions pertinent to astrophysics. The current challenge lies in devising highly precise methods that scale smoothly with A, with a critical emphasis on encompassing the influence of all conceivable reaction channels, including those involving exotic particles.
