Flow angle from intermediate mass fragment measurements
F. Rami, P. Crochet, R. Dona +3
Directed sideward flow of light charged particles and intermediate mass fragments was measured in different symmetric reactions at bombarding energies from 90 to 800 AMeV. The flow…
Xi and Xi-bar Production in 158 GeV/Nucleon Pb+Pb Collisions
The NA49 Collaboration, H. Appelshauser et al
We report measurements of Xi and Xi-bar hyperon absolute yields as a function of rapidity in 158 GeV/c Pb+Pb collisions. At midrapidity, dN/dy = 2.29 +/- 0.12 for Xi, and 0.52 +/-…
Baryon Stopping and Charged Particle Distributions in Central Pb+Pb Collisions at 158 GeV per Nucleon
NA49 Collaboration
Net proton and negative hadron spectra for central \PbPb collisions at 158 GeV per nucleon at the CERN SPS were measured and compared to spectra from lighter systems. Net baryon di…
Identification of baryon resonances in central heavy-ion collisions at energies between 1 and 2 AGeV
M. Eskef, D. Pelte, FOPI collaboration
The mass distributions of baryon resonances populated in near-central collisions of Au on Au and Ni on Ni are deduced by defolding the spectra of charged pions by a method wh…
The end point of the first-order phase transition of the SU(2) gauge-Higgs model on a four-dimensional isotropic lattice
Y. Aoki, F. Csikor, Z. Fodor +1
We report results of a study of the end point of the electroweak phase transition of the SU(2) gauge-Higgs model defined on a four-dimensional isotropic lattice with N_t=2. Finite-…
Where does the hot electroweak phase transition end?
F. Csikor, Z. Fodor, J. Heitger
We give the nonperturbative phase diagram of the four-dimensional hot electroweak phase transition. A systematic extrapolation is done. Our results show that the finite t…
Endpoint of the hot electroweak phase transition
F. Csikor, Z. Fodor, J. Heitger
We give the nonperturbative phase diagram of the four-dimensional hot electroweak phase transition. The Monte-Carlo analysis is done on lattices with different lattice spacings ($a…
The strength of the electroweak phase transition at 80 GeV
F. Csikor, Z. Fodor, J. Heitger
In this letter we present the results of our numerical simulations for the finite temperature electroweak phase transition using the SU(2)-Higgs model on four-dimensional lattices…
Perturbative and non-perturbative studies of the SU(2)-Higgs model on lattices with asymmetric lattice spacings
F. Csikor, Z. Fodor, J. Heitger
We present a calculation of the O(g^2,λ) perturbative corrections to the coupling anisotropies of the SU(2)-Higgs model on lattices with asymmetric lattice spacings. These correcti…
