### Description

Hadronic atoms allow the investigation of strong hadron-nucleon interaction at low energy in nuclear physics. High precision light kaonic atoms X-ray spectroscopy represents a unique tool for performing experiments equivalent to scattering at vanishing relative energies. It aims to determine the antikaon-nucleus interaction at the threshold without the need for extrapolation to zero energy.
The SIDDHARTA-2 collaboration is going to perform the first measurement of kaonic deuterium transitions to the fundamental level. The measurement is mandatory to extract the isospin dependent antikaon-nucleon scattering lengths. The SIDDHARTA-2 experiment is presently installed on the DA$\Phi$NE collider of INFN-LNF. The preliminary results obtained during the machine commissioning phase in preparation for the kaonic deuterium data-taking campaign, and future perspectives for extreme precision kaonic atoms studies at DA$\Phi$NE are presented.
