Figure 1. Constituent quark mass M (dotted line), color superconducting gaps ΔB (red solid line) and Δ (blue dash–dotted line) as functions of μ for ${eB}=4.6{m}_{\pi }^{2}$ . The momentum cutoff is ${\rm{\Lambda }}=602.3\,\mathrm{MeV}$ , and the coupling constants are selected as $G=1.835/{{\rm{\Lambda }}}^{2}$ , H  = 1.74/Λ2, K  = 12.36/Λ5, and $K^{\prime} =4.2K$ .
