H-Dyons and S-Duality
We present a relatively simple argument showing that the H-dyon states required by S-duality of the heterotic string on T 6 are present provided that the BPS dyons required by S-duality of N = 4 supersymmetric Yang-Mills theory are present. We also conjecture and provide evidence that H-dyons at singularities where the nonperturbative gauge symmetry is completely broken are actually BPS dyons.
متن کاملDyons and S-duality in N=4 Supersymmetric Gauge Theory
We analyze the spectrum of dyons in N = 4 supersymmetric Yang-Mills theory with gauge group SU (3) spontaneously broken down to U (1) × U (1). The Higgs fields select a natural basis of simple roots. Acting with S-duality on the W-boson states corresponding to simple roots leads to an orbit of BPS dyon states that are magnetically charged with respect to one of the U (1)'s. The corresponding mo...
متن کاملElectromagnetic Duality, Quaternion and Supersymmetric Gauge Theories of Dyons
Starting with the generalized potentials, currents, field tensors and electromagnetic vector fields of dyons as the complex complex quantities with real and imaginary counter parts as electric and magnetic constituents, we have established the electromagnetic duality for various fields and equations of motion associated with dyons in consistent way. It has been shown that the manifestly covaria...
متن کاملDyons with potentials: duality and black hole thermodynamics
A modified version of the double potential formalism for the electrodynamics of dyons is constructed. Besides the two vector potentials, this manifestly duality invariant formulation involves four additional potentials, scalar potentials which appear as Lagrange multipliers for the electric and magnetic Gauss constraints and potentials for the longitudinal electric and magnetic fields. In this ...
متن کاملDuality-invariant superstring actions.
Worldsheet supersymmetric string action is written in duality invariant form for flat as well as curved backgrounds. First the action in flat backgrounds is written by introducing auxiliary fields. We also give the superfield form of these actions and obtain the off-shell supersymmetry algebra. The action has a modified Lorentz invariance and supersymmetry and reduces to the usual form when the...
