Description
Electroweak form-factors provide information about the internal structure of hadrons; however, short-lived strong resonances are challenging to probe experimentally. In this talk, I will outline a procedure to calculate the elastic form-factors of resonances directly from QCD. This approach relies on computing finite volume matrix elements via lattice QCD, and a formalism to relate these to infinite volume transitions mediated by single local current. After mentioning the key aspects of this formalism, I will describe the decomposition of the two-hadron transitions into generalized form-factors and known kinematic functions. This decomposition allows for a rigorous extraction of elastic form-factors of two-hadron resonances.
