Summary

We present a new method to improve calculations of hot Quantum Chromodynamics (QCD) plasma free energy. This approach effectively resums long-distance effects using a 3D effective field theory and lattice simulations.

Area of Science:

  • High-energy physics
  • Quantum Chromodynamics (QCD)
  • Statistical mechanics

Background:

  • The strict coupling constant expansion for hot QCD plasma free energy exhibits poor convergence and disagreement with lattice data.
  • Existing refined resummations improve lattice agreement but sacrifice formal ties to the coupling constant expansion, especially for long-distance contributions.

Purpose of the Study:

  • To develop a method for resumming dominant long-distance effects in hot QCD plasma.
  • To determine the magnitude of these long-distance effects using lattice Monte Carlo simulations.

Main Methods:

  • Employing a 3D effective field theory to handle dominant long-distance effects.
  • Utilizing simple lattice Monte Carlo simulations for magnitude determination.

Main Results:

  • Successfully resummed dominant long-distance effects in hot QCD plasma.
  • Quantified the magnitude of these effects through lattice simulations.

Conclusions:

  • The 3D effective field theory approach offers a viable way to address limitations in perturbative calculations for hot QCD.
  • This method improves the understanding of QCD plasma properties at high temperatures.
