Fractal Scales in a Schwarzschild Atmosphere
Recently, Glass and Krisch have extended the Vaidya radiating metric to
include both a radiation fluid and a string fluid [1999 Class. Quantum Grav.
vol 16, 1175]. Mass diffusion in the extended Schwarzschild atmosphere was
studied. The continuous solutions of classical diffusive transport are believed
to describe the envelope of underlying fractal behavior. In this work we
examine the classical picture at scales on which fractal behavior might be
evident.Comment: to appear in Class. Quantum Gra

Kaon production and kaon to pion ratio in Au+Au collisions at root(NN)-N-s=130 GeV
Mid-rapidity transverse mass spectra and multiplicity densities of charged and neutral kaons are reported for Au + Au collisions at root(s)NN = 130 GeV at RHIC. The spectra are exponential in transverse mass, with an inverse slope of about 280 MeV in central collisions. The multiplicity densities for these particles scale with the negative hadron pseudo-rapidity density. The charged kaon to pion ratios are K+/pi(-) = 0.161 +/- 0.002(stat) +/-0.024(syst) and K-/pi(-) = 0. 146 +/- 0.002(stat) +/-0.022(syst) for the most central collisions. The K+/pi(-) ratio is lower than the same ratio observed at the SPS while the K-/pi(-) is higher than the SPS result. The ratios are enhanced by about 50% relative to p + p and 0 + p collision data at similar energies. (C) 2004 Elsevier B.V. All rights reserved
