QCD at collider energies

We examine available experimental distributions of transverse energy and transverse momentum, obtained at the CERN pantip collider, in the context of Quantum Chromodynamics. We consider: i) The hadronic transverse energy released during W+- production. This hadronic transverse energy is made out of two components, a soft component which we parametrize using minimum bias events and a semihard component which we calculate from QCD. ii) The transverse momentum of the produced W+-. If the transverse momentum (or the transverse energy) results from a single gluon jet we use the formalism of Dokshitzer-Dyakonov-Troyan, while if it results from multiple gluonic emission we use the formalism of Parisi-Petronzio. iii) The relative transverse momentum of jets. While for W+- production quarks play an essential role, jet production at moderate psub(T) and present energies is dominated by gluon-gluon scattering and therefore we can study the Sudakov form-factor of the gluon. We suggests also how through a Hankel transform of experimental data we can have direct access to the Sudakov form-factors of quarks and gluons
