Resumen:
We present dyon solutions to an SU(2) Dirac-Born-Infeld (DBI) gauge theory coupled to a Higgs triplet. We discuss the existence of a critical value of beta, the Born-Infeld absolute field parameter, below which the solution ceases to exist. We also analyse the effect of modifying the DBI action so as to include the analogous of the theta term, showing that Witten formula for the dyon charge also holds in DBI theories.
