    "abstract": "The generation of finite energy packets of X-waves is analysed in normally\ndispersive cubic media by using an X-wave expansion. The 3D nonlinear\nSchroedinger model is reduced to a 1D equation with anomalous dispersion. Pulse\nsplitting and beam replenishment as observed in experiments with water and Kerr\nmedia are explained in terms of a higher order breathing soliton. The results\npresented also hold in periodic media and Bose-condensed gases.",
