Heterotic solitons
Abstract
An explicit, supersymmetric solution to the lowenergy heterotic string field equations representing an extended soliton with five spatial dimensions is found. This 5brane is dual to heterotic strings in 10 dimensions in the same sense that magnetic charges are dual to electric charges in 4 dimensions. The 5brane core is essentially a YangMills instanton. The worldbrane field theory which describes the 5brane dynamics is found to be heterotic in the sense that it has a chiral representation of supersymmetry and antichiral gauge fermions. A novel interaction between 5branes generated by a heterotic, 2dimensional field theory which lives on 5brane intersection sheets, is discussed. In the context of string compactification, a similar construction is shown to lead to monopoles, strings and membranes in 4 dimensions.
