Enhanced $S$-Factor for the $^{14}\mathrm{N}(p,γ{)}^{15}\mathrm{O}$ Reaction and Its Impact on the Solar Composition Problem

Author(s): X. Chen et al. The solar composition problem has puzzled astrophysicists for more than 20 years. Recent measurements of carbon-nitrogen-oxygen (CNO) neutrinos by the Borexino experiment show a $∼2σ$ tension with the “low-metallicity” determinations. $^{14}\mathrm{N}(p,γ{)}^{15}\mathrm{O}$, the slowest reaction in … [Phys.
