Abstract

A recently published article by Klapdor-Kleingrothaus et al. critiques the limit on the stability of the electron obtained by the Borexino collaboration. We respond here to the criticisms raised by Klapdor-Kleingrothaus and his colleagues, and re-establish that our result is based on very conservative premises and that the “indication of a signal of 1.4 σ” for the decay of the electron in the γ+ν channel, reported by Klapdor-Kleingrothaus and colleagues, is excluded by the Borexino result.
