Abstract

We present the first lattice QCD study of up to 3S and 2P bottomonia at non-zero temperatures. Correlation functions of bottomonia were computed using novel bottomonium operators and a variational technique, within the lattice non-relativistic QCD framework. We analyzed the bottomonium correlation functions based on simple physicallymotivated spectral functions. We found evidence of sequential in-medium modifications, in accordance with the sizes of the bottomonium states.

Thermal broadening of bottomonia: Lattice nonrelativistic QCD with extended operators

Journal Article Larsen, Rasmus ; Meinel, Stefan ; Mukherjee, Swagato ; ... - Physical Review D

We present lattice nonrelativistic QCD calculations of bottomonium correlation functions at temperatures T ≃ 150-350 MeV. The correlation functions were computed using extended bottomonium operators and on background gauge-field configurations for 2+1-flavor QCD having physical kaon and nearly physical pion masses. We analyzed these correlation functions based on simple theoretically motivated parametrizations of the corresponding spectral functions. The results of our analyses are compatible with significant in-medium thermal broadening of the ground state S- and P-wave bottomonia.

Quarkonium in-medium properties from realistic lattice NRQCD

Journal Article Kim, Seyong ; Petreczky, Peter ; Rothkopf, Alexander - Journal of High Energy Physics (Online)

Here, we present the final results of our high statistics study on the properties of bottomonium and charmonium at finite temperature. We focus on the temperature range around the crossover transition 150 ≤ T ≤ 410MeV, relevant for current heavy ion collision experiments. The QCD medium degrees of freedom, which consist of dynamical u,d, and s quarks and gluons are captured by realistic state-of-the art (m _π ≈ 161MeV) lattice QCD simulations of the HotQCD collaboration. For the heavy quarks we deploy the non-relativistic effective field theory of QCD, NRQCD. The in-medium properties of quarkonium are deduced from their spectralmore »« less

Lattice NRQCD study on in-medium bottomonium spectra using a novel Bayesian reconstruction approach

Journal Article Kim, Seyong ; Petreczky, Peter ; Rothkopf, Alexander - AIP Conference Proceedings

We present recent results on the in-medium modification of S- and P-wave bottomonium states around the deconfinement transition. Our study uses lattice QCD with N{sub f} = 2 + 1 light quark flavors to describe the non-perturbative thermal QCD medium between 140MeV < T < 249MeV and deploys lattice regularized non-relativistic QCD (NRQCD) effective field theory to capture the physics of heavy quark bound states immersed therein. The spectral functions of the {sup 3}S{sub 1} (ϒ) and {sup 3}P{sub 1} (χ{sub b1}) bottomonium states are extracted from Euclidean time Monte Carlo simulations using a novel Bayesian prescription, which provides highermore »« less
