The Interacting Gluon Model (IGM) is a tool designed to study energy flow, especially stopping and leading particle spectra, in high energy hadronic collisions. In this model, valence quarks fly through and the gluon clouds of the hadrons interact strongly both in the soft and in the semihard regime. Developing this picture we arrive at a simple description of energy loss, given in terms of few parameters, which accounts for a wide variety of experimental data. This text is a survey of our main results and predictions.

“…The strong coupling constant s is calculated from the two-loop formula with 5 MS = 130 MeV, since this value is also used in the NLO-GRV parametrisation. Changing 5 MS from 130 to 250 MeV only in the s formula increases the two-jet cross-section by factors from 1.4 to 1.07 in the range 3 < E jet T < 16 GeV for p s ee = 130 136 GeV [29].…”

Di-jet production is studied in collisions of quasi-real photons radiated by the LEP beams at e + e centre-of-mass energies p s ee = 161 and 172 GeV. The jets are reconstructed using a cone jet nding algorithm. The angular distributions of direct and double-resolved processes are measured and compared to the predictions of leading order and next-to-leading order perturbative QCD. The jet energy pro les are also studied. The inclusive two-jet cross-section is measured as a function of E jet T and j jet j and compared to next-to-leading order perturbative QCD calculations. The inclusive t w o-jet cross-section as a function of j jet j is compared to the prediction of the leading order Monte Carlo generators PYTHIA and PHOJET. The Monte Carlo predictions are calculated with di erent parametrisations of the parton distributions of the photon. The in uence of the`underlying event' has been studied to reduce the model dependence of the predicted jet cross-sections from the Monte Carlo generators.

Di-Jet production in photon-photon collisions at $\sqrt{s}_{\rm ee}=161$ and 172 GeV

Di-jet production is studied in collisions of quasi-real photons radiated by the LEP beams at e + e − centre-of-mass energies √ s ee = 161 and 172 GeV. The jets are reconstructed using a cone jet finding algorithm. The angular distributions of direct and double-resolved processes are measured and compared to the predictions of leading order and next-to-leading order perturbative QCD. The jet energy profiles are also studied. The inclusive two-jet cross-section is measured as a function of E jet T and |η jet | and compared to next-to-leading order perturbative QCD calculations. The inclusive two-jet cross-section as a function of |η jet | is compared to the prediction of the leading order Monte Carlo generators PYTHIA and PHOJET. The Monte Carlo predictions are calculated with different parametrisations of the parton distributions of the photon. The influence of the 'underlying event' has been studied to reduce the model dependence of the predicted jet cross-sections from the Monte Carlo generators.
