A comment on "Exclusion of the remaining mass window for primordial black holes ...", arXiv:1401.3025

Understand

In arXiv:1401.3025 a new mechanism of energy loss by primordial black holes passing through neutron stars has been proposed, which is more efficient, by many orders of magnitude, than the existing ones.

• In this comment we point out a problem in the calculations of arXiv:1401.3025 that may invalidate the result.
