The tricritical Ising CFT and conformal bootstrap
Johan Henriksson
The paper reviews the tricritical Ising conformal field theory and uses the numerical conformal bootstrap with mixed correlators to locate its fixed points in various dimensions, b…
Massive Gravity is not Positive
Brando Bellazzini, Giulia Isabella, Sara Ricossa +1
We derive new positivity bounds at finite momentum transfer, assuming a large separation between the mass of the lightest particle in the effective theory and the mass gap …
The Two-Loop Four-Graviton Scattering Amplitudes
S. Abreu, F. Febres Cordero, H. Ita +4
We present the analytic form of the two-loop four-graviton scattering amplitudes in Einstein gravity. To remove ultraviolet divergences we include counterterms quadratic and cubic…
No boundary density matrix in elliptic de Sitter dS/
Raphaël Dulac, Zixia Wei
Elliptic de Sitter (dS) spacetime dS is a non-time-orientable spacetime obtained by imposing an antipodal identification to global dS. Unlike QFT on global dS, whose…
Renormalised 3-point functions of stress tensors and conserved currents in CFT
Adam Bzowski, Paul McFadden, Kostas Skenderis
We present a complete momentum-space prescription for the renormalisation of tensorial correlators in conformal field theories. Our discussion covers all 3-point functions of stres…
Locality constraints in AdS without parity
Manuel Loparco, Grégoire Mathys, João Penedones +2
We study bulk locality constraints in quantum field theories in AdS. The known derivation of locality sum rules in AdS does not apply for due to the different sin…
