Bootstrapping string theory EFT
LY Chiang, Y Huang, HC Weng - Journal of High Energy Physics, 2024 - Springer
A bstract We study the space of open string effective field theories by combining the
constraint of unitarity and monodromy relations for the four-point amplitude. The latter is a …

De-projecting the EFThedron
A bstract The space of Wilson coefficients of EFT that can be UV completed into consistent
theories was recently shown to be described analytically by a positive geometry, termed the …

Non-local positivity bounds: islands in Terra Incognita
L Buoninfante, LQ Shao, A Tokareva - arXiv preprint arXiv:2412.08634, 2024 - arxiv.org
The requirements of unitarity and causality lead to significant constraints on the Wilson
coefficients of a EFT expansion, known as positivity bounds. Their standard derivation relies …
