Abstract: (APS)
In a colored-quark and vector-gluon model of hadrons we show that a quark carrying nearly all the momentum of a nucleon (x≈1) must have the same helicity as the nucleon; consequently νW2nνW2p→37 as x→1, not 23 as might naively have been expected. Furthermore as x→1, νW2π∼(1−x)2 and (σLσT)π∼μ2Q−2(1−x)−2+O(g2); the resulting angular dependence for e+e−→h±+X is consistent with present data and has a distinctive form which can be easily tested when better data are available.
