V. Skokov, A. Illarionov, V. Toneev

摘要:

在超相对论量子分子动力学模型(UrQMD)中研究了非中心重离子碰撞产生的磁场.模拟进行了不同的碰撞参量的SPS能量范围内($E_{lab} = 10 - 158 A$ GeV)和RHIC可访问的最高能量。我们证明了在重离子碰撞中出现的磁场在SPS能量范围内具有$eB_y \sim 10^{-1} m_π^2$量级,在RHIC能量范围内具有$eB_y \sim m_π^2$量级。LHC能量的磁场强度的估计值为$eB_y \sim 15 m_π^2$。

英文摘要:

Magnetic fields created in the noncentral heavy-ion collision are studied within a microscopic transport model, namely the Ultrarelativistic Quantum Molecular Dynamics model (UrQMD). Simulations were carried out for different impact parameters within the SPS energy range ($E_{lab} = 10 - 158 A$ GeV) and for highest energies accessible for RHIC. We show that the magnetic field emerging in heavy-ion collisions has the magnitude of the order of $eB_y \sim 10^{-1} m_π^2$ for the SPS energy range and $eB_y \sim m_π^2$ for the RHIC energies. The estimated value of the magnetic field strength for the LHC energy amounts to $eB_y \sim 15 m_π^2$.
