Field theories with no local conservation of the electric charge
Abstract
The gauge theories with a simply connected gauge group and a disconnected subgroup of unbroken symmetries are studied. It is shown that strings exist in such theories. In some cases a particle changes the sign of its electric charge when it goes around the string.
