Description

Recent and upcoming measurements using complementary observables provide an updated scenario towards the description of the low-energy $\bar{\mathrm{K}}$N interactions and the understanding of the nature and structure of the $\mathrm{\Lambda }$(1405).

Among traditional approaches, the first measurement of the Kaonic Deuterium X-rays by SIDDHARTA2 will enable access to the isospin dependence of the interaction. Studies of K${}^{-}$ reactions in light nuclei at DA$\mathrm{\Phi }$NE by AMADEUS and at J-PARC by E-15 provide new measurements of cross sections and scattering amplitudes at very low momentum and the identification and characterization of the $\bar{\mathrm{K}}$NN state.

Two-particle correlation studies in momentum space have been recently demonstrated to be very sensitive to the effects of the final state strong interaction and are applied to K${}^{-}$--p and K${}^0$--p pairs produced in hadron-hadron collisions by the ALICE Collaboration. Such studies are now extended for the first time to Three-Body correlations.
