Bottomonia in the quark-gluon plasma and their production at RHIC and LHC

Bottomonium Production at √ S N N =200 Gev and √ S N N =5.5 Tev

Properties of bottomonia (Υ, χb and Υ ′) in the Quark-Gluon Plasma (QGP) are investigated by assessing inelastic reaction rates and their interplay with open-bottom states (b quarks or B mesons) and color-screening. The latter leads to vanishing quarkonium-binding energies at sufficiently high temperatures (close to the dissolution point), which, in particular, renders standard gluodissociation...

J/psi production in quark-gluon plasma.

We study J/psi production at RHIC and LHC energies with both initial production at energies reached and the BNL Relativistic Heavy Ion Collider (RHIC) and CERN Large Hadron Collider (LHC) with regeneration. We solve the coupled set of transport equations for the J/psi distribution in phase space and the hydrodynamic equation for evolution of quark-gluon plasma. At RHIC, continuous regeneration ...

Bottomonium production at √

Properties of bottomonia (Υ,χb, and Υ ′) in the quark-gluon plasma (QGP) are investigated by assessing inelastic reaction rates and their interplay with open-bottom states (b quarks or B mesons) and color screening. The latter leads to vanishing quarkonium-binding energies at sufficiently high temperatures (close to the dissolution point), which, in particular, renders standard gluo-dissociatio...

Effect of Shadowing on Charm and Bottom Production at RHIC and LHC

We study the influence of nuclear shadowing on the production of heavy quark/anti-quark pair at LHC and RHIC energies. While we do not find any qualitative difference in the production of heavy quarks at RHIC and LHC, a significant reduction in the production cross section of charm and bottom quarks is apparent at high energies. The occurence of bound states such as J/Ψ is suppressed by this re...
