Baryons in a light-front approach

We present a model for baryons based on light-front holography. The effective 3-body Hamiltonian consists of a transverse confining interaction based on the AdS/QCD soft-wall model and a longitudinal confining interaction recently applied to the meson system [1]. We analyze the mass spectrum of nucleons and use the obtained ground-state wave functions to calculate observables such as the electromagnetic form factor and the charge radius. We also compare the model results with experiments and results of holographic QCD. [1] Y. Li, P. Maris, and J.P. Vary, Phys. Rev. D \textbf{96}, 016022 (2017); arXiv:1704.06968
