Updated astrophysical equation-of-state constraints on the color-superconducting gap
Abstract
We summarize and update using new NICER measurements the results of Ref. [1], in which we used various astrophysical neutron-star observations to set an upper bound on the CFL color-superconducting gap in a range of baryon chemical potentials μ B ∈ [2.1, 3.2], above those reached within neutron stars. We also corroborate the "reasonable" constraint from Ref. [1] on the maximum value of the color-superconducting gap by performing a new Bayesian analysis using a prior that extends a two-segment Gaussian process connecting the whole density range between CEFT and pQCD.
