The spin-dependent structure function g1(x) of the deuteron from polarized deep-inelastic muon scattering: Spin Muon Collaboration (SMC)

We present a new measurement of the spin-dependent structure function gd1 of the deuteron from deep inelastic scattering of 190 GeV polarized muons on polarized deuterons. The results are combined with our previous measurements of gd1. A perturbative QCD evolution in next-to-leading order is used to...
