ABSTRACT A spherically symmetric monopole solution is found in SO(5) gauge theory with
Higgs scalar fields in the vector representation in six-dimensional Minkowski
spacetime. The action of the Yang-Mills fields is quartic in field strengths.
The solution saturates the Bogomolny bound and is stable.

    ABSTRACT: In this paper, we establish the existence and uniqueness of the spherically symmetric monopole solutions in SO(5) gauge theory with Higgs scalar fields in the vector representation in six-dimensional Minkowski space–time and obtain sharp asymptotic estimates for the solutions. Our method is based on a dynamical shooting approach that depends on two shooting parameters which provides an effective framework for constructing the generalized monopoles in six-dimensional Minkowski space–time.

    ABSTRACT: We give an exact solution to the generalized self-duality equations suggested by Tchrakian on a six-dimensional twisted space-time and work on the gauge theory SO(3,3) with a higher-derivative coupling term. The coupling term is considered as geometry as well as interaction dependent. The topological properties are also studied.

    ABSTRACT: In the D0-D4-brane system, D0-branes do not tunnel. Instead, they form bound states with the D4-brane, whose ground states are exact. However, the D0-brane quantum mechanics contains a BPS instanton. To what does this solution correspond? We find that such a tunneling solution provides non-perturbative corrections to the Berry phase connection for the first-excited states as the D4-branes are moved adiabatically. We compute this connection for the first four excited states, and show that it gives an emergent SO(5) connection described previously by Tchrakian.
