“…In contrast to previous analytical work, we find a marked difference between the anomalous dimension $1-\gamma$ governing the large transverse momentum behaviour of the gluon distribution for fixed coupling ($\gamma \simeq 0.65$) and for running coupling ($\gamma \sim 0.85$). …”

“…First results obtained with a 160 GeV muon beam on a polarized deuteron target are presented for several physics channels under investigation: in the longitudinal target configuration, a very precise measurement of the structure function $g^{d}_{1}$ and the first precise measurement of $\Delta G/G$, the gluon polarization in a polarized nucleon; in the transverse target mode, the first ever measurements of single spin asymmetries of the deuteron in DIS processes. …”

“…We demonstrate that this implementation of formation time physics alone accounts probabilistically for all analytically known features of the non-abelian LPM-effect, including the characteristic L^2-dependence of average parton energy loss and the characteristic $\sqrt{\omega}$-modification of the gluon energy distribution. Additional kinematic constraints are found to modify these L^2- and $\omega$-dependencies characteristically in accordance with analytical estimates.…”
