Extremal Black Holes from Homotopy Algebras
Jan Gutowski, Chettha Saelim, Martin Wolf
The uniqueness and rigidity of black holes remain central themes in gravitational research. In this work, we investigate the construction of all extremal black hole solutions to th…
Adjusting Higher Chern-Simons Theory
Gianni Gagliardo, Dominik Rist, Christian Saemann +1
A fundamental problem in formulating higher Chern-Simons theories is the construction of a consistent higher gauge theory that circumvents the fake-flatness constraint. Here, we pr…
Full S-matrices and Witten diagrams with (relative) L-infinity algebras
Luigi Alfonsi, Leron Borsten, Hyungrok Kim +2
The -algebra approach to scattering amplitudes elegantly describes the nontrivial part of the -matrix but fails to take into account the trivial part. We argue that th…
Ambitwistor Yang-Mills Theory Revisited
Leron Borsten, Branislav Jurco, Hyungrok Kim +2
Inspired by the Movshev-Mason-Skinner Cauchy-Riemann (CR) ambitwistor approach, we provide a rigorous yet elementary construction of a twisted CR holomorphic Chern-Simons action on…
Boundary Bethe ansatz in massless AdS3
Daniele Bielli, Vasileios Moustakis, Alessandro Torrielli
We construct the boundary algebraic Bethe Ansatz for the AdS3 X S3 X T4 integrable reflection problem restricted to the massless sector. We derive the double-row monodromy and find…
Boundary scattering in massless
Daniele Bielli, Vaibhav Gautam, Vasileios Moustakis +2
We study the boundary integrability problem of the massless sector of string theory. Exploiting the difference-form of the massless scattering theory…
