Baryon Number Violation and String Hadronization
نویسنده
چکیده
In supersymmetric scenarios with broken R-parity, baryon number violating sparticle decays are possible. We report on the development of a framework allowing detailed studies with special attention given to the hadronization phase. In our model, implemented in the Pythia event generator, 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.

متن کاملBaryon Number Violation and String Topologies
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 a...
متن کاملShapes of Cosmic Strings and Baryon Number Violation
The relation between shapes of cosmic string and baryon number violation is investigated. If there exist fermionic zero modes on the string, using bosonization technique, it is possible to obtain the effective action which describes the fermion coupled to the arbitrarily shaped cosmic string. The relation between baryon number and the sum of the writhing number and linking number of the cosmic ...
متن کاملSO(10) cosmic strings and baryon-number violation.
SO(10) cosmic strings formed during the phase transition Spin(10) → SU(5) ×Z2 are studied. Two types of strings — one effectively Abelian and one non-Abelian — are constructed and the string solutions are calculated numerically. The nonAbelian string can catalyze baryon number violation via the “twisting” of the scalar field which causes mixing of leptons and quarks in the fermion multiplet. Th...
متن کاملIs baryon number violated when electroweak strings intercommute?
We reexamine the self-helicity and the intercommutation of electroweak strings. A plausible argument for baryon number conservation when electroweak strings intercommute is presented. The connection between a segment of electroweak string and a sphaleron is also discussed. ⋆ Address after Sep. 1: School of Natural Sciences, Institute for Advanced Study, Princeton, NJ 08540 One of the most basic...
