Instanton-soliton loops in 5D super-Yang-Mills
Constantinos Papageorgakis, Andrew B. Royston
Soliton contributions to perturbative processes in QFT are controlled by a form factor, which depends on the soliton size. We provide a demonstration of this fact in a class of sca…
Scalar Soliton Quantization with Generic Moduli
Constantinos Papageorgakis, Andrew B. Royston
We canonically quantize multi-component scalar field theories in the presence of solitons. This extends results of Tomboulis to general soliton moduli spaces. We derive the quantum…
Brane bending and monopole moduli
Gregory W. Moore, Andrew B. Royston, Dieter Van den Bleeken
We study intersecting brane systems that realize a class of singular monopole configurations in four-dimensional Yang-Mills-Higgs theory. Singular monopoles are solutions to the Bo…
Parameter counting for singular monopoles on R^3
Gregory W. Moore, Andrew B. Royston, Dieter Van den Bleeken
We compute the dimension of the moduli space of gauge-inequivalent solutions to the Bogomolny equation on R^3 with prescribed singularities corresponding to the insertion of a fini…
Revisiting Soliton Contributions to Perturbative Amplitudes
Constantinos Papageorgakis, Andrew B. Royston
It is often said that soliton contributions to perturbative processes in QFT are exponentially suppressed by a form factor. We provide a new derivation of this form factor for a cl…
