Resumen

Using appropriate QCD finite energy sum rules, we discuss the influence of an external magnetic field and baryonic density on the axial-vector coupling constant g_A. This scenario corresponds to a magnetar environment. We found that g_A decreases both as function of the magnetic field strength and the baryonic density. It turns out that at the nuclear density ρ₀ the axial-vector coupling takes the value g_A^⁎≈0.92. Although g_A decreases in general with the magnetic field intensity, g_A^⁎ does not change in a relevant way with the magnetic field.
