We compute the QGP suppression of Upsilon(1s), Upsilon(2s), Upsilon(3s), chi_b1, and chi_b2 states in sqrt(s_NN)=2.76 TeV Pb-Pb collisions. Using the suppression of each of these states, we estimate the inclusive R_AA for the Upsilon(1s)…

The production of $\Upsilon$(2S) and $\Upsilon$(3S) mesons in lead-lead (PbPb) and proton-proton (pp) collisions is studied in their dimuon decay channel using the CMS detector at the LHC. The $\Upsilon$(3S) meson is observed for the first…

In order to disentangle CNM effects from the ``hot'' QGP effects, quarkonium production is studied in p--Pb collisions in which QGP formation is not expected. ALICE has measured the $\Upsilon$ production in p--Pb collisions at $\sqrt{s_{\rm…

We use our mixed hybrid model for the $\Psi(2S)$ state to estimate $\Psi(2S)$ to $J/\Psi(1S)$ suppression in p-Pb collisions, and the $\Upsilon(3S)$ state to estimate $\Upsilon(3S)$ to $\Upsilon(1S)$ suppression in Pb-Pb collisions, and…
