辐射粒子的侧滑

Side-slipping of a radiating particle

Xavier Artru, Guillaume Bignon, Taoufik Qasmi

摘要:

辐射反应被重新审视,首先在一个新的经典aproach,物理粒子4-动量被重新定义为能量动量通量通过未来的光锥,是不平行的4-速度。然后,在半经典方法中,研究表明,当发射光子时,粒子横向于其初始动量“侧滑”,从而证明动量和平均速度之间的非共线性。侧滑最终检查在一个纯量子力学处理的同步辐射。

英文摘要:

Radiation reaction is revisited, first in a new classical aproach, where the physical particle 4-momentum is redefined as the energy-momentum flux across the future light cone and is not parallel to the 4-velocity. Then in a semi-classical approach, it is shown that, when emitting a photon, the particle "side-slips" transversaly to its initial momentum, justifying the non-colinearity between momentum and mean velocity. Side-slipping is finally checked in a pure quantum mechanical treatment of synchrotron radiation.
