Abstract: Background: The term Pygmy Dipole Resonance (PDR) denotes an accumulation of electric dipole excitations below and around the neutron separation threshold. It may be important, e.g., for the nucleosynthesis of heavy nuclei or the symmetry… read more here.

Abstract: We perform joint fits using measurements of the proton structure functions ${F}_{2}(x,{Q}^{2})$ and ${F}_{L}(x,{Q}^{2})$, of the photon structure function ${F}_{2}^{\ensuremath{\gamma}}(x,{Q}^{2})$ and of the total cross sections $\ensuremath{\sigma}(\ensuremath{\gamma}p\ensuremath{\rightarrow}X)$ and $\ensuremath{\sigma}(\ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\rightarrow}X)$. The data is gathered from several… read more here.
