Counting Conformal Correlators
Petr Kravchuk, David Simmons-Duffin
We introduce simple group-theoretic techniques for classifying conformally-invariant tensor-structures. With them, we classify tensor structures of general n-point functions of non…
The Lightcone Bootstrap and the Spectrum of the 3d Ising CFT
David Simmons-Duffin
We compute numerically the dimensions and OPE coefficients of several operators in the 3d Ising CFT, and then try to reverse-engineer the solution to crossing symmetry analytically…
The long flow to freedom
Ofer Aharony, Shlomo S. Razamat, Nathan Seiberg +1
Two-dimensional field theories do not have a moduli space of vacua. Instead, it is common that their low-energy behavior is a sigma model with a target space. When this target spac…
Shortening Anomalies in Supersymmetric Theories
Jaume Gomis, Zohar Komargodski, Hirosi Ooguri +2
We present new anomalies in two-dimensional superconformal theories. They obstruct the shortening conditions of chiral and twisted chiral multiplets at coinc…
Holographic Entanglement Entropy for Gravitational Anomaly in Four Dimensions
Tibra Ali, S. Shajidul Haque, Jeff Murugan
We compute the holographic entanglement entropy for the anomaly polynomial in 3+1 dimensions. Using the perturbative method developed for computing entanglement e…
Non-abelian -theory: Berends-Giele recursion for the -expansion of disk integrals
Carlos R. Mafra, Oliver Schlotterer
We present a recursive method to calculate the -expansion of disk integrals arising in tree-level scattering of open strings which resembles the approach of Berends and Giele t…
