    "abstract": "Helicity amplitudes for the $\\gamma^* N \\to \\Delta$ transition are calculated\nusing the cloudy bag model. A correction for center-of-mass motion is carried\nout using a modified Peierls-Thouless projection method. This reduces the\nmagnitude of the transition amplitudes at small momentum transfer and enhances\nthem at modest momentum transfers. Our calculation shows that the pion cloud\ncontributes substantially to the transition helicity amplitudes, with the final\nresult giving reasonable agreement with the corresponding experimental values.",
