The g1 problem: Deep inelastic electron scattering and the spin of the proton
RL Jaffe, A Manohar - Nuclear Physics B, 1990 - Elsevier
A recent measurement of the spin-dependent structure function of the proton, g 1 p (x, Q 2),
suggest that the quark's spin accounts for little of the proton's spin. We analyze several …
