Description
We have analysed all available data on the non-singlet neutrino structure function χF3 taking into account systematic errors and EMC corrections. A good fit to all data with Q2≥5 (GeV/c)2, W2≥10 (GeV/c)2 is obtained neglecting higher twist contributions, with Λ=0.18±0.07 GeV, corresponding to αs(Q2=25(GeV/c)2)=0.18±0.02. On lowering the cuts to Q2≥3(GeV/c)2, W2≥3(GeV/c)2, we find evidence for a small negative higher-twist term. Incorporating such a term in a simple parametrisation yields an increased Λ value of 0.27±0.05 GeV, corresponding to αs(Q2=25(GeV/c)2)=0.20±0.01. (orig.)
