Comparison of SO(3) and SU(2) lattice gauge theory
Philippe de Forcrand, Oliver Jahn
The Villain form of SO(3) lattice gauge theory is studied and compared to Wilson's SU(2) theory. The topological invariants in SO(3) which correspond to twisted boundary conditions…
Vortex free energies in SO(3) and SU(2) lattice gauge theory
Philippe de Forcrand, Oliver Jahn
Lattice gauge theories with gauge groups SO(3) and SU(2) are compared. The free energy of electric twist, an order parameter for the confinement-deconfinement transition which does…
The helicity amplitudes A and A for the D resonance obtained from the reaction}
GDH-, A2-Collaborations, : +1
The helicity dependence of the reaction has been measured for the first time in the photon energy range from 550 to 790 MeV. The experiment, performed at…
Neutron polarizabilities investigated by quasi-free Compton scattering from the deuteron
K. Kossert, M. Camen, F. Wissmann +20
Measuring Compton scattered photons and recoil neutrons in coincidence, quasi-free Compton scattering by the neutron has been investigated at MAMI (Mainz) at …
