Collisions at Rhic
We study the production of W and Z gauge bosons in proton-proton and proton-neutron collisions up to a center-of-mass energy √ s = 0.5 TeV , in connection with the realistic possibility of having proton-deuteron collisions at RHIC with a high luminosity. We stress the importance of measuring unpolarized cross sections for a better determination of the flavor asymmetry of the sea quarks. Since p...
متن کاملUltra-Peripheral Collisions at RHIC
This presentation summarizes the results on ultra-peripheral collisions obtained at RHIC. It also discusses some aspects of the corresponding electromagnetic interactions in pp and pp collisions. Ultra-peripheral nucleus-nucleus collisions are defined as collisions in which the distance between the nuclei is large enough that no purely hadronic interactions can occur. This roughly means impact ...
متن کاملUltra-Peripheral Collisions with STAR at RHIC
The strong electromagnetic fields of heavy nuclei can produce a wide variety of two-photon and photonuclear reactions at relativistic ion colliders. We present recent results from the STAR collaboration on these ‘ultraperipheral’ interactions, focusing on vector meson production and interferometry, and on ee pair production. The vector meson interferometry occurs because of the symmetric initia...
متن کاملUltraperipheral Collisions at RHIC and LHC
A brief introduction to the physics of ultraperipheral collisions at collider energies is given. Photon-hadron (proton/ nucleus) and photon-photon interactions can be studied in a hitherto unexplored energy regime. 1 Some features of Ultraperipheral Collisions (UPC) Photon-photon and photon-hadron interactions can also be studied in hadron-hadron collisions [1]. This may be surprising since in ...
متن کاملPhotons from nuclear collisions at RHIC energies
We model the hot and dense strongly interacting mater produced in high energy heavy ion collisions using relativistic hydrodynamics. Several different sources of real photons produced during these collisions are considered and their relative importance is assessed. We include contributions from QCD jets, which are allowed to loose and gain energy as they proceed through the hot matter. This is ...
