Quark Asymmetries and Intrinsic Charm in Nucleons
Johan Alwall
We have developed a physical model for the non-perturbative x-shape of parton density functions in the proton, based on Gaussian fluctuations in momenta, and quantum fluctuations o…
MATCHIG: A program for matching charged Higgs boson production at hadron colliders
Johan Alwall
This manual describes how to use the MatCHig code for matching the charged Higgs boson production processes gg->tbH+/- and gb->tH+/-. A negative term, correcting for the double-cou…
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…
Sea Quark Asymmetries in the Nucleon - A physical model for parton distributions in hadrons
Johan Alwall
A physical model for parton densities in hadrons, based on Gaussian momentum fluctuations of partons and hadronic baryon-meson fluctuations, is presented. The model has previously…
An improved description of charged Higgs boson production
Johan Alwall
Many extensions of the Standard Model predict the existence of charged Higgs bosons. In order to be able to find those particles, an accurate description of their production is nee…
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…
