Coulomb Effects on Particle Spectra in Relativistic Nuclear Collisions
Coulomb effects on π± and K± spectra in relativistic nuclear collisions are investigated. At collision energies around 1 GeV the ratio of π− to π is enhanced several times at low transverse momenta but less at ultrarelativistic energies. We describe the ratios at SIS, AGS and SPS energies with simple analytic models as well as more elaborate numerical models incorporating the expansion dynamics...
متن کاملNovel Qcd Effects in Nuclear Collisions*
Heavy ion collisions can provide a novel environment for testing fundamental dynamical processes in QCD, including minijet formation and interactions, formation zone phenomena, color filtering, coherent co-mover interactions, and new higher twist mechanisms which could account for the observed excess production and anomalous nuclear target dependence of heavy flavor production. The possibility ...
متن کاملPolarization Effects in Relativistic Nuclear Pairing
In the present work we discuss the effects of the medium polarization on the nuclear pairing, in the context of the relativistic Hartree-Fock-Bogoliubov (HFB) approximation. The medium polarization effects on the scalar and vector masses, as well on the pairing, as a function of Fermi momentum, are shown for several values of the coupling constants scaled by a parameter x. We find have obtained...
متن کاملVacuum Polarization Effects in Relativistic Nuclear Pairing
In the present work we discuss the contribution of the vacuum polarization on the nuclear pairing, in the context of the relativistic Hartree-Fock-Bogoliubov (HFB) approximation. The polarization effects on the pairing, as a function of Fermi momentum, is shown with the scalar and vector meson-nucleon coupling constants scaled by a parameter x. We have obtained that the nuclear pairing is affec...
متن کاملW and Z polarization effects in hadronic collisions.
A Monte Carlo study of the polar and azimuthal angular distributions of the lepton pair arising from the decay of a W or Z boson produced at high transverse momentum in hadronic collisions is presented. In the absence of cuts on the final state leptons, the lepton angular distribution in the gauge boson rest frame is determined by the gauge boson polarization. Numerical results for the lepton a...
