“…This expansion method has been successfully utilized to study nuclear, atomic and molecular fewbody systems; the wave function of the system is expanded in a series of products of HH basis functions and hyperradial basis functions allowing for a correct description of the large distance components. The predictive power of the HH approach is limited to relatively light mass number, to overcome this limitation the Couple Cluster (CC) theory has been recently combined with the LIT approach to tackle medium and large mass nuclei [83,84]. The photoabsorption cross sections of 16,22 O and 40 Ca and electromagnetic sum rules have been recently computed using the LIT-CC approach in Simonis et al [85].…”

The advent of high precision measurements of neutrinos and their oscillations calls for accurate predictions of their interactions with nuclear targets utilized in the detectors. Over the past decade, ab initio methods based on realistic nuclear interactions and current operators were able to provide accurate description of lepton-nucleus scattering processes. Achieving a comprehensive description of the different reaction mechanisms active in the broad range of energies relevant for oscillation experiments required the introduction of controlled approximations of the nuclear many-body models. In this review, we give an overview of recent developments in the description of electroweak interactions within different approaches and discuss the future perspectives to support the experimental effort in this new precision era.

We demonstrate the capability of coupled-cluster theory to compute the Coulomb sum rule for the 4 He and 16 O nuclei using interactions from chiral effective field theory. We perform several checks, including a few-body benchmark for 4 He. We provide an analysis of the center-of-mass contaminations, which we are able to safely remove. We then compare with other theoretical results and experimental data available in the literature, obtaining a fair agreement. This is a first and necessary step towards initiating a program for computing neutrino-nucleus interactions from first principles and supporting the experimental long-baseline neutrino program with a state-of-the-art theory that can reach medium-mass nuclei.
