We will show how to calculate form factors using a holographic model of
QCD, mainly discussing vector, axial, and pseudoscalar mesons. We
will illustrate the techniques on gravitational form factors (which are
useful for constraining the generalized parton distributions) as well as
quoting the results for electromagnetic form factors. One striking
outcome, comparing the several types of calculated form factors, is that
mesons appear noticeably more compact when measured by the gravitational
form factors than when measured by the charge form factor.
