Final state hadronic rescattering with UrQMD

Hadronic Final State Predictions from Ccfm

Qcd Tests through Hadronic Final-state Measurements *

Modern-day ‘testing’ of (perturbative) QCD is as much about pushing the boundaries of its applicability as about the verification that QCD is the correct theory of hadronic physics. This talk gives a brief discussion of a small selection of topics: factorisation and jets in diffraction, power corrections and event shapes, the apparent excess of b-production in a variety of experiments, and the ...

Final state rescattering as a contribution to B → ργ

We provide a new estimate of the long-distance component to the radiative transition B → ργ. Our mechanism involves the soft-scattering of on-shell hadronic products of nonleptonic B decay, as in the chain B → ρρ → ργ. We employ a phenomenological fit to scattering data to estimate the effect. The specific intermediate states considered here modify the B → ργ decay rate at roughly the 5 → 8% le...

Hadronic final state interactions at ALEPH and OPAL

Bose–Einstein (BE) correlations between identical bosons and Fermi–Dirac (FD) correlations between identical fermions lead to an enhancement or a suppression, respectively, of the particle pairs produced close to each other in phase space. The effect is sensitive to the distribution of particle sources in space and time. The strength of the correlations can be expressed by the two-particle corr...

Properties of the Hadronic Final State in Diiractive Ep Scattering

Hadronic nal states are analyzed with the ZEUS detector for deep inelastic di ractive scattering ep ! eXp, in which the virtual photon dissociates into a hadronic nal state of mass 4 < MX < 35 GeV and the scattered proton, carrying more than 95% of the initial proton momentum, is detected in the Leading Proton Spectrometer. The event shape variables thrust and sphericity are studied as a functi...
