Abstract: A bstractWe use hexagonalization to compute four-point correlation functions of long BPS operators with special R-charge polarizations. We perform the computation at weak coupling and show that at any loop order our correlators can be… read more here.

Abstract: In this paper, we classify four-point local gluon S-matrices in arbitrary dimensions. This is along the same lines as [1] where four-point local photon S-matrices and graviton S-matrices were classified. We do the classification explicitly… read more here.

Abstract: The Sachdev-Ye-Kitaev (SYK) model, a theory of N Majorana fermions with q -body interactions (a.k.a. q -local), becomes in the large q limit a conformally-broken Liouville field theory. Taking this limit preserves many interesting properties… read more here.

DOI: 10.1007/jhep04(2020)105
Abstract: Scattering amplitudes at weak coupling are highly constrained by Lorentz invariance, locality and unitarity, and depend on model details only through coupling constants and the particle content of the theory. For example, four-particle amplitudes are… read more here.

Abstract: Abstract We derive and study Yangian Ward identities for the infinite class of four-point ladder integrals and their Basso-Dixon generalisations. These symmetry equations follow from interpreting the respective Feynman integrals as correlation functions in the… read more here.
