e+e--pair production in Pb-Au collisions at 158 GeV per nucleon
G. Agakichiev, H. Appelshauser, J. Bielcikova +48
We present the combined results on electron-pair production in 158 GeV/n {Pb-Au} (= 17.2 GeV) collisions taken at the CERN SPS in 1995 and 1996, and give a detailed accou…
Semi-Hard Scattering Unraveled from Collective Dynamics by Two-Pion Azimuthal Correlations in 158 A GeV/c Pb + Au Collisions
G. Agakichiev
Elliptic flow and two-particle azimuthal correlations of charged hadrons and high- pions ( 1 GeV/) have been measured close to mid-rapidity in 158A GeV/ Pb+Au coll…
Recent results from Pb-Au collisions at 158 GeV/c per nucleon obtained with the CERES spectrometer
B. Lenkeit, CERES-Collaboration
During the 1996 lead run time, CERES has accumulated 42 million events, corresponding to a factor of 5 more statistics than in 1995 and 2.5 million events of a special photon-run.…
Resonance Contributions to the Electromagnetic Low Energy Constants of Chiral Perturbation Theory
Robert Baur, Res Urech
The effective chiral Lagrangian of the strong and electromagnetic interactions of the pseudoscalar mesons at low energies depends on a set of low energy constants. We determine the…
