DESCRIPTION
Helen Caines MSU QCD Quarks confined within hadrons via strong force v(r) = /r + *r At large r -second term dominates At small r -Coulomb-like part dominates However function of q( mtm transfer) and -> 0 faster than q (or 1/r) -> infinity (called asymptotic freedom) This concept of asymptotic freedom among closely packed coloured objects (q and g) has led to one of the most exciting predictions of QCD !! The formation of a new phase of matter where the colour degrees of freedom are liberated. Quarks and gluons are no longer confined within colour singlets. The Quark-Gluon Plasma!
