Measurement of Charged Particle Multiplicity with the Mulitiplicity and Vertex Detector at the PHENIX Experiment at RHIC

The charged particle multiplicity for the Au-Au collisions at √s =130GeV is measured with the Multiplicity and Vertex Detector (MVD) at PHENIX at RHIC.  The measurement of the charged particle multiplicity using the MVD is compared with measurements made in the PHENIX Pad Chamber and PHENIX Electromagnetic Calorimeters. The centrality dependence of the pseudorapidity density of the charged particles multiplicity is compared with data from the PHOBOS experiment at RHIC, the HIJING model and the High Density QCD saturation model.
