Glueball Production in Peripheral Heavy-Ion Collisions
نویسنده
چکیده
The method of equivalent quanta is applied both to photon-photon and, by analogy, to double pomeron exchange in heavy-ion collisions. This WeizsäckerWilliams approach is used to calculate production cross sections for the glueball candidate fJ(1710) meson via photon-photon and pomeron-pomeron fusion in peripheral heavy-ion collisions at both RHIC and LHC energies. The impact-parameter dependence for total and elastic cross sections are presented, and are compared to results for proton-proton collisions. Typeset using REVTEX ∗Email: [email protected]

Glueballs in Peripheral Heavy-Ion Collisions
We estimate the cross-section for glueball production in peripheral heavy-ion collisions through two-photon and double-Pomeron exchange, at energies that will be available at RHIC and LHC. Glueballs will be produced at large rates, opening the possibility to study decays with very small branching ratios. In particular, we discuss the possibility of observing the subprocess γγ(PP ) → G → γγ. e-m...
متن کاملHadronic Physics in Peripheral Heavy Ion Collisions
We discuss the production of hadronic resonances in very peripheral heavy ion collisions, where the ions collide with impact parameter larger than twice the nuclear radius and remain intact after the collision. We compare the resonance production through two-photon and double Pomeron exchange, showing that when we impose the condition for a peripheral interaction the process dominates over the ...
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 کاملQuantum Interferometry in ρ Production in Ultra-Peripheral Heavy Ion Collisions
In ρ photoproduction in ultra-peripheral heavy ion collisions, either ion can be the photon emitter or the target. The two possibilities are indistinguishable, and they should be able to interfere, reducing rho production at low transverse momentum, pT < h̄/〈b〉, where 〈b〉 is the median impact parameter. The two ρ production points are separated by 〈b〉 ≈ 18−46 fm, while the ρ decay before travell...
متن کاملModeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
