Effective Lagrangian for non-Abelian two-dimensional topological field theory (2022)
Journal Article
Srisangyingcharoen, P., & Mansfield, P. (2022). Effective Lagrangian for non-Abelian two-dimensional topological field theory. Nuclear Physics B, 980(115798), Article 115798. https://doi.org/10.1016/j.nuclphysb.2022.115798

We develop a systematic approach to obtain an effective Lagrangian for 2D non-Abelian topological BF theory. A general expression is presented in a diagrammatic representation containing solely scalar fields. Expressions for the and effective actions...

Plahte diagrams for string scattering amplitudes (2021)
Journal Article
Srisangyingcharoen, P., & Mansfield, P. (2021). Plahte diagrams for string scattering amplitudes. Journal of High Energy Physics, 2021(4), Article 17. https://doi.org/10.1007/jhep04%282021%29017

Plahte identities are monodromy relations between open string scattering amplitudes at tree level derived from the Koba-Nielsen formula. We represent these identities by polygons in the complex plane. These diagrams make manifest the appearance of si... Read More about Plahte diagrams for string scattering amplitudes.
