نویسنده
چکیده
Two cylindrical forward TPC detectors are described which were constructed to extend the phase space coverage of the STAR experiment to the region 2.5 < |η| < 4.0. For optimal use of the available space and in order to cope with the high track density of central Au+Au collisions at RHIC, a novel design was developed using radial drift in a low diffusion gas. From prototype measurements a 2-track resolution of 1 2 mm is expected.

New measurements of short-range and long-range two-particle correlations, azimuthal anisotropy, and event-by-event fluctuations from the STAR experiment for √ s N N = 130 and 200 GeV Au+Au collisions are summarized. Striking evidence is presented for large, non-statistical fluctuations in mean transverse momentum. Descriptions of the data in terms of phenomenological source function models are ...
