The first results from Au-Au collisions at √ sNN =130 GeV obtained with the PHENIX detector in the Year 2000 run at RHIC are presented. The mid-rapidity charged particle multiplicity and transverse energy per participating nucleon rise steadily with the number of participants, such that ET /N ch remains relatively constant as a function of centrality. Identified charged hadron spectra as well as ¯ p/p and K + /K − ratios are discussed. Charged particle and neutral pion transverse momentum distributions in peripheral nuclear collisions are consistent with point-like scaling. The spectra at high pt from central collisions are significantly suppressed when compared to a simple superposition of binary nucleon-nucleon collisions.
