Description

Baryon-number generation due to the decay of particle-antiparticle pairs created from cosmic string loops is studied. In the situation when cusp evaporation occurs a significant baryon asymmetry (baryon/entropy ≅ 10-4 ε: ε is a net baryon asymmetry generated from one particle-antiparticle pair) can be generated.
