Muon-Deuteron Deep Inelastic Scattering

We have measured deep inelastic muon-deuteron scattering in the range 0.4<Q²<3.4 and 1.6<ν<5.6 GeV. We have extracted the neutron structure function and find that νW₂ⁿ differs significantly from νW₂ᵖ, as also found in e-d scattering. To compare μ-d and e-d scattering we form the ratio r(Q²)=(νW₂)_μᵈ(νW₂)ₑᵈ=N(1+Q²Λ²)^-2 and find N=0.925±0.038 and 1Λ²=-0.019±0.016.
