Title: Lightcone Bootstrap at higher-points

Abstract: Higher-point functions of scalar operators are a rich observable in CFTs, as they contain OPE data involving multiple spinning operators. In this talk, I will derive the lightcone blocks for five- and six-point functions in the snowflake channel and use them to bootstrap these correlators in the lightcone limit. As a result, I will determine the large spin expansion of OPE coefficients involving two or three spinning operators, which can then be checked in simple theories. Finally, I will point out many open directions of research involving CFT higher-point functions.
