Response to a critique of the Borexino result in "A new experimental limit for the stability of the electron" by H.V. Klapdor-Kleingrothaus, I.V. Krivosheina and I.V. Titkova

TL;DR

This paper defends the Borexino collaboration's electron stability limit against critiques, reaffirming that their conservative analysis excludes the claimed 1.4 sigma signal of electron decay reported by Klapdor-Kleingrothaus et al.

Contribution

It provides a rebuttal to specific criticisms, reinforcing the validity of Borexino's conservative approach and its exclusion of the claimed electron decay signal.

Findings

Borexino's limit is based on conservative premises.

The claimed 1.4 sigma signal is excluded by Borexino data.

The paper clarifies the robustness of Borexino's results.

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 $\sigma$" for the decay of the electron in the $\gamma+\nu$ channel, reported by Klapdor-Kleingrothaus and colleagues, is excluded by the Borexino result.
