    • The parton distributions are parameterized at a reference scale μ02 by xqNS(x,μ02)= ANSxη1(1- x)η2+ BNSxη3, xqSI(x,μ02)= xqNS(x,μ02)+ Asea(1- x)ηsea andxg(x,μ02)=Ag(1-x)ηg and evolved to all other values of μ2 using the GLAP [10] evolution equations. ANS is constrained by the fermion conservation sum rule∫dxxxqNS(x)=3, and Ag is constrained by the momentum sum rule∫dx[xqSI(x)+xg(x)]=1. The final fit parameter is the strong coupling constant, given byΛMS, for a total of eight fit parameters. At μ02=1 GeV2/c2, the parameters areΛMS=0.210±0.021 GeV/c, η1=0.947±0.027, η2=3.81±0.059, η3=0.0519±0.0064, BNS=0.0210±0.0039, Asea=1.404±0.047, ηsea=6.49±0.22, ηg=3.18±0.70, where the errors are statistical only
