Description
The formalism of transverse-momentum-dependent (TMD) factorization in Quantum Chromodynamics (QCD) is the cornerstone of all phenomenological studies of the hadron structure and of the hadronization mechanism in three-dimensional momentum space. TMD factorization allows us to connect specific measurements of cross sections or asymmetries with TMD parton distribution functions (PDFs) and fragmentation functions (FF), which characterize the “internal structure” of the QCD bound states (pions, nucleons, etc.) in terms of the elementary degrees of freedom of the theory, quarks and gluons. Given the nonperturbative nature of QCD at the scales comparable to hadron masses, these TMD functions need to be studied by complementing perturbation theory with nonperturbative inputs, such as models, lattice QCD computations, or determinations from experimental data.
The project aims at relieving this tension between theory and measurements, by improving specific aspects of the formalism at low energies and quantifying the relevance of the improvements at the phenomenological level.
