OPE for all Helicity Amplitudes
Benjamin Basso, Joao Caetano, Lucia Cordova +2
We extend the Operator Product Expansion (OPE) for scattering amplitudes in planar N=4 SYM to account for all possible helicities of the external states. This is done by constructi…
Thermodynamics of the BMN matrix model at strong coupling
Miguel S. Costa, Lauren Greenspan, Joao Penedones +1
We construct the black hole geometry dual to the deconfined phase of the BMN matrix model at strong 't Hooft coupling. We approach this solution from the limit of large temperature…
Flux and Hall states in ABJM with dynamical flavors
Yago Bea, Niko Jokela, Matthew Lippert +2
We study the physics of probe D6-branes with quantized internal worldvolume flux in the ABJM background with unquenched massless flavors. This flux breaks parity in the (2+1)-dimen…
Conformal correlators of mixed-symmetry tensors
Miguel S. Costa, Tobias Hansen
We generalize the embedding formalism for conformal field theories to the case of general operators with mixed symmetry. The index-free notation encoding symmetric tensors as polyn…
Four point function of stress-tensor multiplet at strong coupling
Vasco Gonçalves
In this short note we use the flat space limit and the relation between the 4-pt correlation function of the bottom and top components of the stress tensor multiplet to constraint…
Factorization of Mellin amplitudes
Vasco Gonçalves, João Penedones, Emilio Trevisani
We introduce Mellin amplitudes for correlation functions of scalar operators and one operator with spin in conformal field theories (CFT) in general dimension. We show that Mel…
