Study of the strong interaction in p-d system and of deuteron production in pp collisions

This thesis focuses on two main research topics. Firstly, it explores the strong interaction in the proton-deuteron (p-d) system. This is done by measuring two-body correlations through the femtoscopy technique with p-d pairs in pp collision at LHC. The measured correlation is sensitive to the dynamics of three nucleons and can be explained only by the full three-body calculations. Secondly, it investigates the production of deuterons employing the coalescence model in pp collisions.
