The authors' main claim We demonstrate that quark matter in the color-flavor locked phase of QCD is rigorously electrically neutral, despite the unequal quark masses, and even in the presence of an electron chemical potential.

We demonstrate that quark matter in the color-flavor locked phase of QCD is rigorously electrically neutral, despite the unequal quark masses, and even in the presence of an electron chemical potential. As long as the strange quark mass and the electron chemical potential do not preclude the color-flavor locked phase, quark matter is automatically neutral. No electrons are required and none are admitted.

The paper
Original abstract
We demonstrate that quark matter in the color-flavor locked phase of QCD is rigorously electrically neutral, despite the unequal quark masses, and even in the presence of an electron chemical potential. As long as the strange quark mass and the electron chemical potential do not preclude the color-flavor locked phase, quark matter is automatically neutral. No electrons are required and none are admitted.

Referring to [ref] , we first rewrite the thermodynamic potential $Ω$ of the superconducting quark matter [ref] in a general form with the pQCD correction [ref] included: [equation] where $μ$ and $μ_e$ are the respective average quark and electron chemical potentials.

For completeness, however, we add that the functional form of the expansion [ref] at LO/LO agrees with the one obtained for the pressure in Nambu-Jona-Lasinio-type model calculations at that order, see, e.g., Refs. [ref] .] In all cases, the overall scale of the gap is fixed to be $Δ_∗ = 100$.
