    "abstract": "A parameter-free evaluation of the $N - P_{11}(1440)$ electromagnetic\ntransition form factors is performed within a light-front constituent quark\nmodel, using for the first time the eigenfunctions of a mass operator which\ngenerates a large amount of configuration mixing in baryon wave functions. A\none-body electromagnetic current, which includes the phenomenological\nconstituent quark form factors already determined from an analysis of pion and\nnucleon experimental data, is adopted. For $Q^2$ up to few $(GeV/c)^2$, at\nvariance with the enhancement found in the elastic channel, the effect of\nconfiguration mixing results in a significant suppression of the calculated\nhelicity amplitudes with respect to both relativistic and non-relativistic\ncalculations, based on a simple gaussian-like ansatz for the baryon wave\nfunctions.",
