Abstract
Conformal Regge theory predicts the existence of analytically continued conformal field theory data for complex spin. How could this work when there are so many more operators with large spin compared to small spin? Using planar N=4 SYM as a test ground, we find a simple physical picture. Operators do organize themselves into analytic families but the continuation of the higher families have zeros in their structure operator product expansion constants for lower integer spins. They thus decouple. Newton's interpolation series technique is perfectly suited to this physical problem and will allow us to explore the complex spin half-plane.

We are especially grateful to Simon Caron-Huot for a most inspiring discussion in 2018, at the annual Simons Bootstrap Collaboration meeting at the Perimeter Institute. Some of the results obtained in this Letter were somehow anticipated by Simon already at that time (albeit using different tools/ideas). We thank several participants of the 2022 Simons bootstrap collaboration meeting for reminding us of the important Ref. [8].
