Baryon Number Violation and String Topologies Torbjörn Sjöstrand and Peter Z. Skands LU TP 02-46, hep-ph/0212264. Nucl.Phys.B. 659:243(2003). In supersymmetric scenarios with broken $R$-parity, baryon number violating sparticle decays become possible. In order to search for such decays, a good understanding of expected event properties is essential. We here develop a complete framework that allows detailed studies. Special attention is given to the hadronization phase, wherein the baryon number violating vertex is associated with the appearance of a junction in the colour confinement field. This allows us to tell where to look for the extra (anti)baryon directly associated with the baryon number violating decay.
