Pionic susceptibility for charged pions in asymmetric nuclei
M. Urban, J. Wambach
At low energies the particle-hole (ph) part of the pionic susceptibility in isospin-symmetric nuclear matter is known to behave very differently from the susceptibility in finite n…
Self energies of the pion and the delta isobar from the ^3He(e,e'pi^+)^3H reaction
M. Kohl, M. Kuss, C. Rangacharyulu +7
In a kinematically complete experiment at the Mainz microtron MAMI, pion angular distributions of the He(e,e'H reaction have been measured in the excitation region of t…
Vector and axial-vector correlators in a chirally symmetric model
M. Urban, M. Buballa, J. Wambach
We present a chirally symmetric hadronic model for the vector and axial-vector correlators in vacuum. The dominant contributions to these correlators come from intermediate pions,…
Modifications of the Rho Meson from the Virtual Pion Cloud in Hot and Dense Matter
M. Urban, M. Buballa, R. Rapp +1
The modification of the rho-meson self-energy due to the coupling to in-medium pions is calculated consistently at finite baryon density and temperature, keeping the full 3-momentu…
Momentum Dependence of the Pion Cloud for Rho Mesons in Nuclear Matter
M. Urban, M. Buballa, R. Rapp +1
We extend hadronic models for rho-meson propagation in cold nuclear matter via coupling to in-medium pions to include finite three-momentum. Special care is taken to preserve gauge…
A Microscopic Calculation of Photoabsorption Cross Sections on Protons and Nuclei
R. Rapp, M. Urban, M. Buballa +1
A recently developed model for -meson propagation in dense hadronic matter is applied to total photoabsorption cross sections in -proton and -nucleus reactions. Within the…
