Comments on lumps from RG flows

Abstract

In this note we investigate the proposal of Ellwood [1] and one of the authors et al. [2] to construct a string field theory solution describing the endpoint of an RG flow from a reference BCFT0 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.
