Zusammenfassung

We study 2Q+1-strings connecting two static charges Q in (2+1)-d SU(2) Yang-Mills theory. While the fundamental 2-string between two charges Q = 1/2 is unbreakable, the adjoint 3-string connecting two charges Q = 1 can break. When a 4-string is stretched beyond a critical length, it decays into a 2-string by gluon pair creation. When a 5-string is stretched, it first decays into a 3-string, which eventually breaks completely. The energy of the screened charges at the ends of a string is well described by a phenomenological constituent gluon model.
