Abstract

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^-4ε{lunate}: ε{lunate} is a net baryon asymmetry generated from one particle-antiparticle pair) can be generated.
