Heavy Ion Collisions by STAR
We present the first measurement of reconstructed jets in ultra-relativistic heavy ion collisions. Utilizing the large coverage of the STAR Time Projection Chamber and Electromagnetic Calorimeter, we apply several modern jet reconstruction algorithms and background subtraction techniques and explore their systematic uncertainties in heavy ion events. The differential spectrum for inclusive jet ...
متن کاملHighlights from STAR: probing the early medium in heavy ion collisions
We present highlights of recent results from the STAR Collaboration at RHIC, focusing on the properties of the early medium created in heavy ion collisions. We emphasize the strangeness production including the observation of a hypernucleus (the hypertriton), the observation of reaction-plane-dependent angular correlation of charged particles searching for local strong parity violation effects ...
متن کاملUltra-peripheral Heavy Ion Collisions at Star
Ultra-peripheral heavy ion collisions involve long range electromagnetic interactions at impact parameters larger than twice the nuclear radius, where the strong nucleon-nuecleon interactions are uneffective. We present recent results from the STAR collaboration on these ultra-peripheral interactions likes incoherent 0 ρ production in deuteron-gold collisions and interferometry in gold-gold col...
متن کاملPhotoproduction at the Relativistic Heavy Ion Collider with STAR
The strong electromagnetic fields of short duration associated with relativistic heavy ions make a heavy-ion collider a unique tool to study two-photon and photonuclear collisions. In this talk, we introduce the principles of photoproduction at hadron colliders, review recent results from RHIC on meson and e+e− production. At RHIC, STAR has studied exclusive ρ0 vector meson production and ρ0 pr...
متن کاملPhotoproduction in Ultra-Peripheral Heavy Ion Collisions at STAR
We present recent STAR results on photoproduction in ultra-peripheral relativistic heavy ion collisions. In these collisions the impact parameter of the beam particles is larger than the sum of their nuclear radii, so that they interact via their long-range Coulomb fields. STAR has measured the production of ρ(770) mesons in exclusive reactions as well as in processes with mutual nuclear excita...
