A plethora of new precision measurements of (anti)(hyper)nuclei and final state interactions among nucleons or hyperons has been carried out recently at CERN at the LHC and SPS accelerator complexes. These measurements have strong implications for several astrophysics topics. The JENAA workshop on nuclear physics at CERN and connections to astrophysics aims to provide a platform to discuss current and future research directions.

This workshop focuses on two main avenues. The first is on antinuclei measurements at accelerator facilities, including production and annihilation cross-sections, studies of the production mechanisms, and their impact on searches for new physics with cosmic rays (e.g., dark matter). The nuclear physics program at CERN provides crucial measurements for interpreting results from satellite or balloon experiments.

The second avenue deals with the recent measurements of final state interactions between nucleons and hyperons and hypernuclei properties at the LHC. Such measurements are critical to computing the equation of state of dense hadronic matter and bear important implications for understanding neutron stars. Two- but also three-body strong final state interactions can be accessed at the LHC and this allows to update the equation of state calculations to more realistic scenarios. 

In this workshop we will discuss the state of the art of the experimental measurements and the observation of cosmic antinuclei and neutron star properties to enhance the connection between fields and also propose new experimental and theoretical studies in this context.
