We present a model for baryons based on three constituent quarks using light-front holography together with basis light-front quantization (BLFQ). The work is generalized from the method which originally developed for meson systems using a constituent quark and an antiquark. We construct an effective 3-body Hamiltonian, which consists of a transverse confining interaction based on the Ads/QCD soft-wall model, and a longitudinal confining interaction which was first applied to mesons. We employ this model for the proton by calculating its form factor F1(q2). The results are compared with experimental measurements and other theoretical methods. We develop generalized Jacobi coordinates, as well as a generalized longitudinal confinement, that will enable this model to be generalized to systems with more than three constituent quarks.
