Measuring Distance and Properties of the Milky Way's Central Supermassive Black Hole with Stellar Orbits
A. M. Ghez, S. Salim, N. N. Weinberg +10
We report new precision measurements of the properties of our Galaxy's supermassive black hole. Based on astrometric (1995-2007) and radial velocity (2000-2007) measurements from t…
Event-by-event fluctuations of average transverse momentum in central Pb+Pb collisions at 158 GeV per nucleon
NA49 collaboration, H. Appelshauser
We present first data on event-by-event fluctuations in the average transverse momentum of charged particles produced in Pb+Pb collisions at the CERN SPS. This measurement provides…
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…
