Femtoscopy study of the kaon-deuteron interaction

Abstract

The kaon-deuteron interaction has been studied through different models. The one developed in this work constructs the K−d interaction by folding K−n and K−p local potentials derived from a chiral effective Lagrangian. This approach is probed using the femtoscopy technique and the K−d correlation function data provided by the ALICE collaboration @ LHC. Results show an excellent agreement with experimental data and provide evidence of a quasi-bound state inherited from the Λ(1405) resonance, and also lay out further possibilities of improving the model to constrain the physical values of the femtoscopic source.
