Abstract
We present results on charged particle production at very low transverse momenta in the 15% most central Au + Au collisions at roots(NN) = 200 GeV obtained with the PHOBOS detector at the Relativistic Heavy Ion Collider. The invariant yields were measured at midrapidity in the transverse momentum ranges from 30 to 50 MeV/c for charged pions, 90 to 130 MeV/c for charged kaons and 140 to 210 MeV/c for protons and antiprotons. No significant enhancement in low transverse momentum particle production is observed as compared to extrapolations of identified particle spectra measured at an intermediate P-T range. The spectra tend to flatten at low p(T), consistent with the expectations of transverse expansion of the system.
