Electroexcitation of theN*(1440) in the relativistic constituent quark model

Relativistic ${\mathit{P}}_{11}$ wave functions are constructed that have 2S and 1S character in the static limit. Their constraint-free electromagnetic N-${\mathit{N}}^{\mathrm{*}}$ transition form factors are calculated from a conserved current. A gauge condition at ${\mathit{q}}^2$=0 is met by a three-quark current. The 2S helicity amplitudes are too large compared with the sparse data, while the 1S results are an order too low. A mixture of the 1S and 2S states agrees with the electroproduction but misses the photon point.
