Description
The low-energy QCD, the theory within the Standard Model describing the strong interaction, is still missing fundamental experimental results in order to achieve a breakthrough in its understanding. Among these experimental results, the low-energy kaon-nucleon/nuclei interaction studies are playing a key-role, with important consequences going from particle and nuclear physics to astrophysics (neutron stars and their equation of state).
Combining the excellent quality of the low-energy kaon beam delivered by the DAΦNE collider in Frascati (Italy) with new experimental techniques, as fast and very precise X-ray detectors, like the Silicon Drift Detectors, we have performed unprecedented measurements in the low-energy strangeness sector in the framework of the SIDDHARTA Collaboration and are presently running the SIDDHARTA-2 experiment for the challenging kaonic atoms measurements, such as kaonic deuterium first measurement.
I shall introduce the physics of kaonic atoms, the experiment and the first results, and discuss future plans.
The experiments at the DAΦNE collider represents an unique opportunity in the world to, finally, unlock the secrets of the QCD in the strangeness sector and contribute to better understand the role of strangeness in the Universe, from nuclei to the stars.
