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 physically-motivated spectral functions. We found evidence of sequential in-medium modifications, in accordance with the sizes of the bottomonium states.

  1. Anisotropic excited bottomonia from a basis of smeared operators

    hep-lat 2025-02 conditional novelty 6.0 of 10

    Excited bottomonia masses and widths are extracted from lattice NRQCD using a smeared-operator GEVP, showing a width hierarchy and a slowly melting ground state.

  2. In-medium bottomonium properties from lattice NRQCD calculations with extended meson operators

    hep-lat 2025-01 conditional novelty 6.0 of 10

    Bottomonium masses do not shift in the quark-gluon plasma up to 250 MeV, but thermal widths are nonzero and highly sensitive to the assumed spectral function shape.

  3. Non-relativistic QCD Study of Excited Bottomonia at Finite Temperatures on a Fine Lattice

    hep-lat 2025-01 conditional novelty 4.0 of 10

    Excited bottomonia in a quark-gluon plasma acquire temperature-dependent widths with no significant mass shifts, according to a Gaussian model fit to lattice NRQCD correlators.
