Regge in Wonderland
Abstract
We study the asymptotic behavior of large-spin operators in conformal field theories by placing the theory on a pp-wave background. In this setting, the diagonal three-point coefficients involving two large-spin operators and a light operator are mapped to thermal one-point functions on the pp-wave. We predict these one-point functions in the two complementary regimes of high and low temperature, corresponding respectively to the total twist parametrically above and below an appropriate spin-dependent scale. In particular, at high temperature, we derive their asymptotic behavior using thermal effective field theory, while at low temperature, we obtain universal formulas that can be matched directly to predictions from the analytic bootstrap. We test these results in free theories on the pp-wave. Finally, we solve the large-N O(N) model numerically, finding agreement with our predictions for both the one-point function and the free energy density in the high- and low-temperature regimes.
