Whirlpools in the sea: Polarization of antiquarks in a spinning proton
Journal Article
·
· Phys. Rev. Lett.; (United States)
We argue that the sea of virtual quark-antiquark pairs in a proton is polarized. Quantum chromodynamics allows a valence quark to emit a gluon which then produces pairs. If the parent quark in this process exhibits a (1-x)/sup 3/ behavior as x ..-->.. 1 then the antiquark with helicity the same as the original quark will have a leading (1-x)/sup 5/ distribution. Implications for the counting rules and for polarized Drell-Yan annihilation are discussed.
