We show that it is proportional to the identity and that it takes the same form as for AdS3 \u00d7 S3 \u00d7 T4 and for flat space. Based on this, we make a conjecture for the exact worldsheet S matrix and derive the mirror thermodynamic Bethe ansatz (TBA) equations describing the spectrum. Despite a non-trivial vacuum energy, they can be solved in closed form and coincide with a simple set of Bethe ansatz equations \u2014 again much like AdS3 \u00d7 S3 \u00d7 T4 and flat space. This suggests that the model may have an integrable spin-chain interpretation. Finally, as a check of our proposal, we compute the spectrum from the worldsheet CFT in the case of highest-weight representations of the underlying Ka\u010d-Moody algebras, and show that the mirror-TBA prediction matches it on the nose."
