| Abstract: | Comparison of the predictionsof asymptotically free gauge theories on ? 1n vW2(x, q2)|? 1n q2 in the small x region with recent data on high-energy muon-hadron scattering allows a fairly direct determination of the effective coupling constant. The result is α(q2)?0.21/[1 + 0.14 1n q2 (GeV2)]. This is much smaller than previous indirect estimates. |
