Quark form factors and leading double logarithms in quantum chromodynamics
Journal Article
·
· Phys. Rev., D; (United States)
Perturbative quantum-chromodynamic corrections involving the emission of gluons which are both soft and collinear are discussed for both hadronic production of lepton pairs and e/sup +/e/sup -/ annihilation. The result is an exponential, double-logarithmic quark ''form factor.'' The differences between previous analyses are clarified and the possible experimental observation of the form factor is discussed and illustrated.
