Hadronic transition form factors (TFFs) play a crucial role in the determination of Standard Model parameters from data and for probing potential effects of physics beyond the Standard Model (BSM). At the same time, they also contain dynamical information about the inner structure of the hadrons in question. In principle, TFFs can be calculated ab initio and with great precision using lattice QCD. However, presently and for the immediate future this is not the case for hadronic TFFs of non-local operators, or when hadronic final-state interactions and rescattering effects are important for TFFs of local operators. In such cases, we can use the analyticity properties of the hadronic TFFs and relate them to other and simpler known hadronic matrix elements using standard techniques, such as e.g. hadronic dispersion relations. In this project we aim to improve the descriptions of hadronic TFFs arising in two distinct fields of particle physics: low-energy decay and transition processes, and (semi)leptonic B meson decays.
