Circular-viewing rainbow holography
Completely differ to common plate rainbow holography, a circular-viewing rainbow holography which is viewed in the direction approximately parallel to the holographic plate is elaborated. The viewing-angle of this rainbow hologram made by this technique is 360°. The experimental result and its analysis are presented.
Abstract A very promising spin physics programme will be soon on the way at the BNL Relativistic Heavy Ion Collider (RHIC). By studying the spin asymmetries for various processes (single photon, single jet and W ± production), we will compare the different predictions obtained using some sets of polarized parton distributions, available in the recent literature. We will put some emphasise on the analysis of the anticipated errors, given the event rates expected from this high luminosity new machine and the current acceptance for the detector systems at RHIC.
