Abstract

We present some recent results obtained in the study of the color magnetic and electric screening masses in the QCD plasma. In particular, we discuss how the masses get modified by strong external fields which are expected to be created in physical situations such as heavy-ion collisions.

Highlights

  • Strong magnetic fields of the order of the QCD scale can be found in many physical situations and phenomena such as the early universe [1, 2] or non-central heavy ion collisions [3, 4]

  • We discuss how the masses get modified by strong external fields which are expected to be created in physical situations such as heavy-ion collisions

  • In the presence of an external magnetic field, our data suggest that the screening masses grow as a function of |e|B, according to the observations pointed out previously by looking at the behaviour of the magnetic and electric correlators

Summary

Introduction

Strong magnetic fields of the order of the QCD scale can be found in many physical situations and phenomena such as the early universe [1, 2] or non-central heavy ion collisions [3, 4]. In these contexts, fields with intensities up to 1016 Tesla (|e|B ∼ 1 GeV2) are expected to be produced. Fields with intensities up to 1016 Tesla (|e|B ∼ 1 GeV2) are expected to be produced They may influence the properties of strongly interacting matter and many theoretical studies have been devoted to this argument
