Subthreshold Antiproton Spectra in Relativistic Heavy Ion Collisions
Richard Wittmann, Ulrich Heinz
We study the structure of antiproton spectra at extreme subthreshold bombarding energies using a thermodynamic picture. Antiproton production processes and final state interactions…
Transverse Momentum Dependence of Hanbury-Brown/Twiss Correlation Radii
Urs Achim Wiedemann, Pierre Scotto, Ulrich Heinz
The transverse momentum dependence of Hanbury-Brown/Twiss (HBT) interferometry radii for 2-body correlation functions provides experimental access to the collective dynamics in hea…
The ``Out-Longitudinal'' Cross Term and Other Model Independent Features of the Two-Particle HBT Correlation Function
Scott Chapman, Pierre Scotto, Ulrich Heinz
Using two specific models and a model independent formalism, we show that an ``out-longitudinal'' cross term should be included in any gaussian fits to correlation data. In additio…
The Role of Strangeness in Ultrarelativistic Nuclear Collisions
Josef Sollfrank, Ulrich Heinz
We review the progress in understanding the strange particle yields in nuclear collisions and their role in signalling quark-gluon plasma formation. We report on new insights into…
Extracting Source Parameters from Gaussian Fits to Two-Particle Correlations
Scott Chapman, J. Rayford Nix, Ulrich Heinz
Using a quadratic saddle-point approximation, we show how information about a particle-emitting source can be extracted from gaussian fits to two-particle correlation data. Althoug…
