    "abstract": "We address the question about the velocity of signals carried by Bessel beams\nwave packets propagating in vacuum and having well defined wavefronts in time.\nWe find that this problem is analogous to that of propagation of usual plane\nwave packets within dispersive media and conclude that the signal velocity can\nnot be superluminal.",
