【 摘 要 】

We compute the suppression of the bottomonia states Υ ( 1 S ), Υ ( 2 S ), Υ ( 3 S ),χ b ( 1 P ) ,χ b ( 2 P ) , andχ b ( 3 P )states in Large Hadron Collider (LHC) sN N= 5.023 TeV Pb-Pb collisions. For the background evolution we use 3+1d anisotropic hydrodynamics with conditions extrapolated from sN N= 2.76 TeV and we self-consistently compute bottomonia decay rates including non-equilibrium corrections to the interaction potential. For our final results, we make predictions for RA Aas function of centrality, rapidity, and p T for the Υ ( 1 S ) and Υ ( 2 S ) states, including feed down effects. In order to assess the dependence on some of the model assumptions, we vary the shear viscosity-to-entropy density ratio, 4 π η / s ∈ { 1 , 2 , 3 }, and the initial momentum-space anisotropy parameter,ξ 0∈{ 0 , 10 , 50 } , while holding the total light hadron multiplicity fixed.
