Bootstrapping string theory EFT
Li-Yuan Chiang, Yu-tin Huang, He-Chen Weng
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 reflection…
The Geometry of the Modular Bootstrap
Li-Yuan Chiang, Tzu-Chen Huang, Yu-tin Huang +3
We explore the geometry behind the modular bootstrap and its image in the space of Taylor coefficients of the torus partition function. In the first part, we identify the geometry…
De-projecting the EFThedron
Li-Yuan Chiang, Yu-tin Huang, Laurentiu Rodina +1
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 EFThedr…
(Non)-projective bounds on gravitational EFT
Li-Yuan Chiang, Yu-tin Huang, Wei Li +2
In this paper we study both projective and non-projective constraints on four-dimensional gravitational effective fields theories implied from unitarity, causality and crossing, as…
Into the EFThedron and UV constraints from IR consistency
Li-Yuan Chiang, Yu-tin Huang, Wei Li +2
Recently it was proposed that the theory space of effective field theories with consistent UV completions can be described as a positive geometry, termed the EFThedron. In this pap…
