Measuring transversity densities in singly polarized hadron-hadron and lepton-hadron collisions
We show how the transverse polarization of a quark initiating a jet can be probed by the azimuthal distribution of two hadrons (of large z) in the jet. This permits a twist 2 asymmetry in hard processes when only one of the initial particles is polarized transversely. Applications to hadron-hadron and lepton-hadron scattering are discussed.
متن کاملHadron Production in Hadron-Hadron and Lepton-Hadron Collisions
We review a recent global analysis of inclusive single-charged-hadron production in high-energy colliding-beam experiments, which is performed at nextto-leading order (NLO) in the parton model of quantum chromodynamics endowed with nonperturbative fragmentation functions (FFs). Comparisons of pp data from CERN SppS and the Fermilab Tevatron and γp data from DESY HERA with the corresponding NLO ...
متن کاملTheoretical aspects of singly polarized hadron - hadron collisions § ∗
The special role played by singly polarized high-energy hadron-hadron collisions in Spin Physics is discussed: In such processes, the measured and the calculated quantities can be and have been directly compared with each other — without data-extrapolation and without sum rules. It is in this kind of processes, where significant asymmetries (up to 30-40%) have been observed. It is also in this ...

متن کاملInelastic diffraction and color-singlet gluon-clusters in high-energy hadron-hadron and lepton-hadron collisions
It is proposed, that “the colorless objects” which manifest themselves in largerapidity-gap events are color-singlet gluon-clusters due to self-organized criticality, and that optical-geometrical concepts and methods are useful in examing the spacetime properties of such objects. A simple analytical expression for the t-dependence of the inelastic single diffractive cross section dσ/dt (t is th...
