Abstract: I will present our first findings on D-meson femtoscopy by using the TROIA framework. Our analysis employs unitarized effective hadron interactions derived from an off-shell T-matrix calculation in a coupled-channel basis. We have obtained correlation functions of heavy-light mesons accounting for Coulomb interaction in the relevant channels, and have analyzed the impact of inelastic processes. I will present a set of results that can be directly compared to experimental data from the ALICE experiment. Our study also encompasses predictions involving novel channels, including strange mesons and their vector siblings. Our original research contributes to a deeper understanding of heavy meson-light meson interactions via femtoscopy measurements in proton-proton collisions.
