Heavy-heavy-light asymptotics from thermal correlators
We revisit the calculation of spectral densities and heavy-heavy-light (HHL)
operator product expansion (OPE) coefficients in three-dimensional conformal field theories
using thermal one-point functions on S^1 x S^2. We develop systematic expansions in the regime of large ∆_H, and we validate our analytic tools by comparing the results with free field theories.
