Diffraction, Good-Walker, and the BFKL pomeron

Gustafson, Gösta LU (2010) Gribov-80 Memorial Workshop on Quantum Chromodynamics and Beyond, Miramare, Trieste, 26-28 May 2010
Abstract
The proton has a substructure in terms of parton cascades, which in a high energy collision fills the whole rapidity range between projectile and target. In the Good–Walker formalism the fluctuations in the cascades will give rise to diffractive excitation. Within the Lund Dipole Cascade model, it is in this way possible to reproduce diffractive excitation in pp collisions and DIS. In central pp collisions the fluctuations, and thus diffractive excitation, is suppressed by saturation. This leads to factorization breaking when comparing pp scattering and DIS. The results shows a multi-regge behaviour, with a bare pomeron pole with α(0) = 1.21, α′ = 0.2 GeV-2, and an almost constant triple-pomeron coupling g3P ≈ 0.3 GeV-1.
