Comments on Lumps from RG flows

Erler, Theodore, Maccaferri, Carlo

Understand

In this note we investigate the proposal of Ellwood and one of the authors et al.

to construct a string field theory solution describing the endpoint of an RG flow from a reference BCFT to a target BCFT*.
We show that the proposed class of solutions suffers from an anomaly in the equations of motion.
Nevertheless, the gauge invariant action exactly reproduces the expected shift in energy.
