Limiting fragmentation and $\phi$ meson production at RHIC
Abstract
The PHOBOS's limiting fragmentation etc. three empirical scaling rules for charged multiplicity in collisions at RHIC are investigated by a hadron and string cascade model LUCIAE. Similar studies are performed for the meson exploring its production mechanism via comparing with the charged multiplicity. The LUCIAE results for charged multiplicity are compatible with PHOBOS observations. However, for the meson the three empirical scaling rules are either kept only or kept better in the LUCIAE calculations without reduction mechanism of the quark suppression extra introduced for the strangeness in LUCIAE model. These results seem indicating a universal production mechanism for charged particle and meson in string fragmentation regime. It is discussed that the PHOBOS's empirical scaling rules are model dependent indeed.
