36. A Bootstrap Bridge Between QCD and Gravity

Andrea Guerrieri

15/12/2023, 09:00

The numerical S-matrix Bootstrap aims at establishing non-perturbative universal bounds on physical observables that can be extracted from scattering amplitudes in any dimension. In this talk, I will focus on dimensions greater or equal to four, focusing on three main topics: no-go theorems for supersymmetric quantum gravity, rigorous model dependent bounds on Higgs couplings, and...

37. Abelian Insights on Kinematic Algebras

Certain non-abelian gauge theories obey so-called BCJ duality, whereby their colour algebra is accompanied by a second algebra involving kinematic degrees of freedom, and which in turn allows amplitudes in such theories to be double-copied to gravity. For special theories in particular gauges, the kinematic algebra can be ascertained exactly, and corresponds to an (infinitely dimensional) Lie...
