Description
SIDDHARTA-2 concludes a 30-year quest on measuring the k-p and k-n strong interaction at threshold, manifested in light exotic atoms as a relevant shift and a widening of the fundamental level. The collaboration successfully carried out the first measurement ever of the kaonic deuterium transitions, which, combined with the SIDDHARTA results on kaonic hydrogen in 2009, allows extracting the isospin-dependent kaon-nucleon scattering lengths, quantities fundamental to understanding the low-energy QCD in the strangeness sector and in particular the chiral symmetry breaking mechanism. A series of innovative techniques developed during the decades by the collaboration will be presented, together with the most recent results and future plans to employ the methods for other fundamental investigations, like the determination of the still uncertain charged kaon mass and measuring the transitions of other light and medium-weight kaonic atoms, with impact on various physics topics, from astrophysics to quantum field theory.
