Description

We present estimates of transition form factors for some nucleon resonances $N^\ast$, based on two independent frameworks. We start with the presentations of results based on light-front holography, for the nucleon and the Roper. Later on, we discuss some results based on a covariant quark model for several resonances $N^\ast$. In general the estimates compare well with data for
intermediate and large square momentum transfer ($Q^2 > 2$ GeV$^2$).
