Abstract
We present an axially symmetric vortex ring dyons solutions of the SU(2) Yang‐Mills‐Higgs theory. These vortex rings carry electric charges that are determined by a parameter, −1⩽η⩽1.−1⩽η⩽1. They possess vanishing magnetic charge and are located at a ring centered around the z‐axis where the Higgs field vanishes. These stationary vortex ring dyon solutions possess finite energy but they do not satisfy the first order Bogomol’nyi equations. In the Bogomol’nyi‐Prasad‐Sommerfield (BPS) limit where the Higgs field potential is zero, the time component of the gauge field is parallel to the Higgs field in isospace. The total energy, net electric charge and diameter of the vortex ring increase exponentially to infinity when η approaches ±1.±1. On the contrary, when λ = 1,λ = 1, all these three values reach their critical value as η approaches ±1.
