TL;DR
This paper explores how strong magnetic fields influence QCD phase transitions, including pion mass reduction, magnetic catalysis, and charge fluctuations, based on lattice QCD simulations.
Contribution
It presents new lattice QCD results on conserved charge fluctuations and correlations under strong magnetic fields, linking these to phase structure changes.
Findings
Neutral pion mass decreases in magnetic fields
Magnetic catalysis occurs with reduced transition temperature
Charge fluctuations and correlations are affected by magnetic fields
Abstract
In this proceedings we discuss the natural connection between the reduction of neutral pion mass in the vacuum, and the magnetic catalysis as well as the reduction of transition temperature in the external magnetic field. We also present the first results on fluctuations of and correlations among conserved charges in strong magnetic fields from lattice QCD computations.
