Magnetic Field Effects on Hadron Yields and Fluctuations
We explore the impact of an external magnetic field on hadron yields and fluctuations in a thermalized system within the hadron resonance gas (HRG) model using an expanded Thermal-FIST package. The magnetic field sizably enhances the final proton-to-pion (p/π) ratio due to △(1232)++ decay feeddown i...

| description | We explore the impact of an external magnetic field on hadron yields and fluctuations in a thermalized system within the hadron resonance gas (HRG) model using an expanded Thermal-FIST package. The magnetic field sizably enhances the final proton-to-pion (p/π) ratio due to △(1232)++ decay feeddown indicating that this ratio may serve as a potential magnetometer for freeze- out conditions. At the same time, magnetic field does not generate additional dynamical fluctuations of hadron numbers. This suggests that fluctuations in heavy-ion collisions provide limited additional information about the magnetic field beyond what is already inferred from mean multiplicities. |
