Quark asymmetries in the proton from a model for parton densities
Johan Alwall, Gunnar Ingelman
Based on quantum fluctuations in momentum and of the proton into meson-baryon pairs, we develop a physical model for the non-perturbative x-shape of parton density functions in the…
Generalized VDM and F_2 data at low Q^2
Johan Alwall, Gunnar Ingelman
The generalised vector meson dominance model (GVDM) gives a good description of F_2 data at very low Q^2. At intermediate Q^2 a GVDM component avoids problems when applying the lar…
Improved mapping of ccbar onto charmonium states
C. Brenner Mariotto, M. B. Gay Ducati, G. Ingelman
We discuss the relative rates of different charmonium states and introduce an improved model for mapping the continuous ccbar mass spectrum on the physical charmonium resonances.
Soft and hard QCD in charmonium production
C. Brenner Mariotto, M. B. Gay Ducati, G. Ingelman
Hard and soft QCD dynamics are both important in charmonium hadroproduction, as presented here through a next-to-leading order QCD matrix element calculation combined with the colo…
Diffractive Higgs production: Soft Colour Interactions perspective
N. Timneanu, R. Enberg, G. Ingelman
We briefly present the soft colour interaction models which are successful in reproducing a multitude of diffractive hard scattering data, and give predictions for diffractive Higg…
Hard and soft QCD in charmonium production
C. B. Mariotto, M. B. Gay Ducati, G. Ingelman
We show that both hard perturbative and soft non-perturbative QCD effects are important in hadroproduction of charmonium. Observed and distributions of J/psi in fix…
