Twisted sectors from plane partitions

Understand

Twisted sectors arise naturally in the bosonic higher spin CFTs at their free points, as well as in the associated symmetric orbifolds.

• We identify the coset representations of the twisted sector states using the description of W_\infty representations in terms of plane partitions.
• We confirm these proposals by a microscopic null-vector analysis, and by matching the excitation spectrum of these representations with the orbifold prediction.
