The HADES experiment, installed at GSI, Darmstadt, measures di-electron production in A+A, p/π + N and p/π + A collisions. Here, the π and η Dalitz decays have been reconstructed in the exclusive p + p reaction at 2.2 GeV to form a reference cocktail for long-lived di-electron sources. In the C+C reaction at 1 and 2 GeV/u, these long-lived sources have been subtracted from the measured inclusiv...

Jefferson Lab experiment E01-012 measured the 3He spin-structure functions and virtual photon asymmetries in the resonance region in the momentum transfer range 1.0<Q2<4.0 (GeV/c)2. Our data, when compared with existing deep inelastic scattering data, were used to test quark-hadron duality in g1 and A1 for 3He and the neutron. In addition, preliminary results on the 3He spin-structure function ...

We determine the dimension of certain q-ary algebraic-geometric codes, extending previous results of Van Der Vlugt for p-ary algebraic-geometric trace codes.
