High momentum transfer, short distances

  1. Dec 1, 2008 #1
    Hi there!

    I have some problems understanding the connection between high momentum transfer and short distance behavior. I know that the QCD coupling goes to zero as the momentum transfer [itex]Q^2[/itex] approaches infinity. Most introductory HEP textbooks say that this means that the quarks in the nucleons are almost non-interacting because the behavior at high momentum transfer determines the short distance behavior. This leads me to the conclusion that the quarks in the nucleon only exchange high momenta. Why should this be true?

    Best, ledamage
