Abstract

The matrix element V_ud of the CKM matrix can be determined by two independent measurements in neutron decay: the neutron lifetime τ_n and the ratio of coupling constants λ = g_A/g_V , which is most precisely determined by measurements of the beta asymmetry angular correlation coefficient A. We present recent progress on the determination of these coupling constants.
