Structure of cosmic strings for a gauged B-L symmetry and two Higgs fields
José Antonio GarcÃa-Hernández, Victor Muñoz-Vitelly, Wolfgang Bietenholz
In the Standard Model, the difference between the baryon number and the lepton number is conserved, which represents a symmetry that is global and exact, and therefore unna…
