论文摘要
受到散射幅度的经典限制的最新进展的启发，我们表明可以从外壳电流的经典极限获得硬热环。硬热环的经典性是通过将经典波数与软颗粒关联的。我们在QED，QCD和重力中计算这些电流的经典极限。我们的建议不涉及引入鬼魂。
Inspired by recent progress on classical limits of scattering amplitudes, we show that hard thermal loops can be obtained from classical limits of off-shell currents. The classicality of hard thermal loops is made manifest by associating classical wavenumbers to soft particles. We compute the classical limit of these currents in QED, QCD and gravity. Our proposal does not involve the introduction of ghosts.
