Description
Transverse-momentum-dependent parton distribution functions (TMDs) provide multidimensional information on the internal structure of hadrons and play an important role in ongoing and future studies of hadron tomography. In this talk, I will present recent investigations of the leading-twist TMDs of light pseudoscalar mesons within the continuum Schwinger function approach. Particular attention is given to the pion and kaon, for which the unpolarized TMD and the Boer-Mulders function constitute the complete set of leading-twist quark TMDs. Results for both distributions will be discussed, highlighting their nonperturbative structure and the role of dynamical chiral symmetry breaking and emergent hadron mass. These studies provide a unified picture of the transverse momentum structure of light mesons and offer theoretical benchmarks for future phenomenological and experimental investigations.
