Quark charges and nuclear β-decay

Nature volume 257, pages 189–193 (1975)Cite this article

Abstract

The rate of β-decay is affected by the charges, Q, of the nucleon's constituent quarks. The Salam–Weinberg scheme permits us, in a spirit of adventurous naivety, to conclude that Q̄ = 0.20±0.10; this combines with electron and neutrino data to suggest individual quark charges: Qp = 0.69±0.07, Qn = −0.29±0.15.
