A theoretical <particle physicist> who established <asymptotic freedom> for a class of <Yang-Mills theories> in 1973. The effective interaction becomes weak at sufficiently high <energy>, allowing <perturbation theory> to be useful in a theory that has strong interactions at longer distances. This supplies a key theoretical route from <quantum chromodynamics> to quantitative short-distance predictions.<Reliable Perturbative Results for Strong Interactions? by Hugh David Politzer>[Abstract and short-distance perturbative calculation]{ref}
