Kalb-Ramond solitons in basonic string theory Sussman, Benjamin Jacob


A soliton of the Kalb-Ramond field in closed bosonic string theory is introduced. Under appropriate configurations the cosmological constant becomes a periodic function of the Kalb-Ramond field. This vacuum degeneracy permits the formation of sine- Gordon solitons. The energy and length scale of the soliton is inversely proportional to the string coupling constant g[sub s]. The stability of the the solitons is discussed and it is shown that these objects are stable.
