title: A hybrid solitary-conical self-guided light beam in self-focusing media.
abstract: In addition to subluminal solitons and superluminal conical beams, self-focusing media also support a luminal nonspreading beam with hybrid solitary-conical properties. Its existence reveals that spatial solitons may also have a conical structure, and vice versa.
