Contribution

It introduces a method to obtain solitonic strings in (2,0) theory with a new interaction term and explores their moduli space and dimensional reduction.

Findings

Derived a zero force condition between parallel strings.

Computed the moduli space metric as R^4 at large separation.

Connected the six-dimensional strings to four-dimensional dyons via compactification.

Abstract

We show how one can get solitonic strings in a six-dimensional (2,0) supersymmetric theory by incorporating a nonlinear interaction term. We derive a zero force condition between parallel strings, and compute a metric on a moduli space which is $R^4$ when the strings are far apart. When compactifying the strings on a two-torus we show that, in the limit of vanishing two-torus, one regains the moduli space of two widely separated dyons of equal magnetic charges in four dimensions.
