We study the spectrum of meson masses in large N_c QCD_2 governed by the renowned ‘t Hooft integral equation. In [https://arxiv.org/abs/2409.11324] we generalize… -

The two-point correlation function of a massive field, measured along an observer's worldline in de Sitter (dS), decays exponentially in time. Meanwhile, every dS… -

Over 50 years ago, 't Hooft observed the similarity between the Feynman diagram expansion of a large N gauge theory and the topological expansion of a string… -

Conformal field theories can be seen as well-defined mathematical objects constrained by the bootstrap axioms. An interesting case is families of CFTs interpolating…
