The end of the nucleon-spin crisis
Autor: Povh, Bogdan, Walcher, Thomas
The small fraction of the quark polarization of the nucleon obtained in deep inelastic lepton scattering is a consequence of a wrong assumption on the flux of polarized virtual photons in the analysis of the data. The true flux of polarized photons i

Pion fluctuation in deep inelastic scattering
Autor: Bunyatyan, Armen, Povh, Bogdan
Publikováno v: Eur.Phys.J. A27 (2006) 359-364
The forward neutron production in the ep collisions at 300 GeV measured by H1 and ZEUS Collaborations at DESY has been used to estimate the total probability for proton fluctuation into n pi^+ and p pi^0. The probability found is on the order of 30%.

Report
Nuclear Shadowing and the Proton Structure Function at Small x
Autor: Kopeliovich, Boris, Povh, Bogdan
A new scaling variable is introduced in terms of which nuclear shadowing in deep-inelastic scattering is universal, i.e. independent of $A$, $Q^2$ and $x$. This variable can be interpreted as a measure of the number of gluons probed by the hadronic f
