From Correlators to massive amplitudes in N = 4 SYM

Regular Seminar Frank Coronado (ETH Zurich)

at:
14:00 QMUL
room G. O. Jones 610 and Zoom
abstract:

In planar N=4 SYM, massless scattering amplitudes are dual to null polygonal Wilson loops (T-duality) or the same as the four-dimensional null limit of stress-tensor correlators. I will present a (conjectured) generalization of this duality which equates correlators of determinant operators, in a special ten-dimensional null limit, with massive scattering amplitudes in the Coulomb branch of N=4. This determinant operator is a generating function of all half-BPS single-traces operators. By taming it on twistor space I will show its correlators have ten dimensional poles which combine 4d space-time and 6d R-charge kinematics.

Ten dimensional hidden symmetry of N=4 SYM

room Zoom, instructions in abstract
abstract:

I will present a generating function for the loop-integrands of all four-point functions of protected single-trace operators in $\mathcal{N}=4$ SYM. This function enjoys a ten-dimensional symmetry that combines spacetime and the internal R-charge symmetries. By considering a 10D light-like limit I will establish a relationship between the simplest four-point correlators (octagons) and four-particle amplitudes. --- Part of the London Integrability Journal Club.
