Production of quark pairs from classical gluon fields
F. Gelis, K. Kajantie, T. Lappi
We compute by numerical integration of the Dirac equation the number of quark-antiquark pairs produced in the classical color fields of colliding ultrarelativistic nuclei. Results…
Modeling the momentum distributions of annihilating electron-positron pairs in solids
I. Makkonen, M. Hakala, M. J. Puska
Measuring the Doppler broadening of the positron annihilation radiation or the angular correlation between the two annihilation gamma quanta reflects the momentum distribution of e…
Smallness of the imaginary part of the eta-nucleus scattering length
J. A. Niskanen
In two recent analyses of eta meson production a very small imaginary part was obtained for the eta-He3 scattering length, which is in contradiction with most theoretical predictio…
Chemical thermalization in relativistic heavy ion collisions
F. Gelis, K. Kajantie, T. Lappi
We compute by numerical integration of the Dirac equation the number of quark-antiquark pairs initially produced in the classical color fields of colliding ultrarelativistic nuclei…
