dc.description.abstractIn recent years, there has been increasing interest in hadronic excitations. So how would one go about exploring hadron resonances and their structure in the context of Lattice QCD? We outline how the variational method can be utilised for form factor calculations. This variational approach not only provides us with a method for extracting excited state hadron form factors, but also results in dramatic improvement in ground state calculations through the removal of excited state contaminations. Here we present both these aspects in the context of π and ρ meson form factors.
