In my seminar, I will cover the dispersive analysis of final state interactions and its application to BESIII data. I will provide an in-depth look at the challenges associated with different production and decay mechanisms. Our collaboration with BESIII aims to extract pion generalized polarizabilities and meson transition form factors involving $\pi\pi, \pi\eta,~\rm{ and}~K\bar{K}$ systems, which are needed for (g-2)_mu. Additionally, we collaborate with BESIII in the study of exotic XYZ states, focusing on the charged charmonium-like Zc states and their production through hidden flavor decays. Using $\pi\pi,~\rm{ and}~K\bar{K}$ final state interaction and helicity formalism for the 3-body decays, we aim to accurately determine the resonance parameters of Zc states, including their spin and parity.
