We substantially refine our previously developed model for the suppression of Upsilon mesons in the quark-gluon plasma (QGP) formed in 2.76 TeV PbPb collisions at the LHC. It accounts for gluodissociation of the six bottomium states Y(nS), chi_b(nP) with n = 1,2,3, collisional damping of these states as described in a complex potential, screening of the real part of the potential, and the subsequent decay cascade. In the hydrodynamical calculation of the expanding fireball, we take into account… 

Bottomia physics at RHIC and LHC

In UU collisions at RHIC energies and PbPb collisions at LHC energies the suppression of ϒ mesons in the hot quark-gluon medium (QGP) versus reduced feed-down is investigated. Our model encompasses

Bottomonium spectroscopy in the quark–gluon plasma

The spectroscopic properties of heavy quarkonia are substantially different in the quark-gluon plasma (QGP) that is created in relativistic heavy-ion collisions as compared to the vacuum situation

Bottomia suppression in PbPb collisions at the LHC

The suppression of ϒ-mesons in the hot quark-gluon medium in PbPb collisions relative to scaled pp at = 2.76 TeV is accounted for in a model that encompasses gluodissociation, collisional damping,

Hot-medium effects on ϒ yields in p-Pb and Pb-Pb collisions

The modification of bottomonia yields in Pb–Pb and p–Pb collisions at LHC energies with respect to the expectation from p–p is investigated in a theoretical approach. Dissociation of the ϒ(nS ) and

Aspects of Relativistic Heavy-Ion Collisions

The rapid thermalization of quarks and gluons in the initial stages of relativistic heavy-ion collisions is treated using analytic solutions of a nonlinear diffusion equation with schematic initial

Hadron production and bottomia suppression at the LHC

Hadron production in relativistic heavy-ion collisions at LHC energies is in- vestigated. After a brief consideration of stopping, particle production is accounted for in a relativistic diffusion

Charmonium suppression in ultra-relativistic proton–proton collisions at LHC energies: a hint for QGP in small systems

Proton–proton (pp) collision has been considered as a baseline to study the system produced in relativistic heavy-ion (AA) collisions with the basic assumption that no thermal medium is formed in pp



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

We study the production of bottomonium states in heavy-ion reactions at collider energies available at RHIC and LHC. We employ an earlier constructed rate equation approach which accounts for both

ϒ suppression in PbPb collisions at energies available at the CERN Large Hadron Collider

We suggest that the combined effect of screening, gluon-induced dissociation, collisional damping, and reduced feed-down explains most of the sequential suppression of $\ensuremath{\Upsilon}(nS)$

By means of effective field theory techniques, we study the modifications of some properties of weakly coupled heavy quarkonium states propagating through a quark-gluon plasma at temperatures much

We investigate the decay cascade of the ϒ(nS) meson including the newly found χb(3P) state in pp and PbPb collisions at LHC energies. The main goal is to quantitatively determine the additional

Using the two-component model that includes charmonium production from initial nucleon-nucleon hard scattering and regeneration in the produced quark-gluon plasma, we study $J/\psi$ production in

The thermal suppression of the Υ(1s) and χ(b1) states in √s(NN) = 2.76 TeV Pb-Pb collisions is computed and the total R(AA) for theΥ( 1s) state as a function of centrality, rapidity, and transverse momentum is estimated.
