Bulk Landau Pole and Unitarity of Dual Conformal Field Theory
Ivo Sachs, Pierre Vanhove
The singlet sector of the -model in AdS at large-, gives rise to a dual conformal field theory on the conformal boundary of AdS, which is a deformation of th…
Spin fields for the spinning particle
E. Boffo, I. Sachs
We propose an analogue of spin fields for the relativistic RNS-particle in 4 dimensions, in order to describe Ramond-Ramond states as "two-particle" excitations on the world line.…
Analytical evaluation of cosmological correlation functions
T. Heckelbacher, I. Sachs, E. Skvortsov +1
Using the Schwinger-Keldysh-formalism, reformulated in arXiv:2108.01695 as an effective field theory in Euclidean anti-de Sitter, we evaluate the one-loop cosmological four-point f…
Dark Energy and the Spinning Superparticle
Daniel Bockisch, Ivo Sachs
We revisit the theory of background fields constructed on the BRST-algebra of a spinning particle with worldline supersymmetry, whose spectrum contains the graviton…
Analytical evaluation of AdS Witten diagrams as flat space multi-loop Feynman integrals
Till Heckelbacher, Ivo Sachs, Evgeny Skvortsov +1
We describe a systematic approach for the evaluation of Witten diagrams for multi-loop scattering amplitudes of a conformally coupled scalar -theory in Euclidean AdS, by r…
Proca Theory from the Spinning Worldline
Matthias Carosi, Ivo Sachs
We obtain Proca field theory from the quantisation of the supersymmetric worldline upon supplementing the graded BRST-algebra with an extra multiplet of oscillators…
