Pion and nucleon structure functions near x=1

In a colored-quark and vector-gluon model of hadrons we show that a quark carrying nearly all the momentum of a nucleon (x1) must have the same helicity as the nucleon; consequently W2nW2p37 as x1, not 23 as might naively have been expected. Furthermore as x1, W2(1-x)2 and (LT)2Q-2(1-x)-2+O(g2); the resulting angular dependence for ee-hX is consistent with present data and has a distinctive form which can be easily tested when better data are available.
