Excited bottomonia in quark-gluon plasma from lattice QCD

TL;DR

This study uses lattice QCD to analyze how bottomonium states behave in quark-gluon plasma at different temperatures, revealing sequential modifications related to their sizes.

Contribution

First lattice QCD analysis of excited bottomonia states at finite temperature using novel operators and spectral function analysis.

Findings

Evidence of sequential in-medium modifications of bottomonia

Correlation functions reflect size-dependent melting

Supports theoretical predictions of bottomonium behavior in plasma

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.
