Jet Photoproduction in Peripheral Heavy-Ion Collisions
In peripheral relativistic heavy ion collisions at the Large Hadron Collider, jet+jet and photon+jet final states can be produced when a photon from the virtual photon field surrounding the nucleus interacts with a parton in the opposite nucleus (direct production). The virtual photon may also fluctuate into states with multiple gluons and qq pairs (resolved production), opening more channels f...
متن کاملPhotoproduction in Ultra-Peripheral Heavy-Ion Collisions
The strong electromagnetic fields present in ultra-peripheral collisions of heavy-ions offer a possibility to study two-photon and photonuclear collisions complementary to similar studies with lepton beams but over an increased photon energy range. This presentation[1] will give an overview of photoproduction at hadron colliders.
متن کاملHeavy Quark Photoproduction in Ultra-peripheral Heavy Ion Collisions
Heavy quarks are copiously produced in ultra-peripheral heavy ion collisions. In the strong electromagnetic fields, cc and bb are produced by photonuclear and two-photon interactions; hadroproduction can occur in grazing interactions. We present the total cross sections, quark transverse momentum and rapidity distributions, as well as the QQ invariant mass spectra from the three production chan...
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...
متن کاملPhotoproduction of top in peripheral heavy ion collisions
In relativistic heavy ion collisions, top quarks can be produced by photongluon fusion when a photon from the Weizsäcker-Williams virtual photon field of one nucleus interacts with a gluon in the other nucleus. Photoproduction with heavy ions at the Large Hadron Collider (LHC) will be the first accessible non-hadronic top production channel. We calculate the tt photoproduction cross sections, p...
