洛伦兹不变相对速度与相对论性双星碰撞

Lorentz invariant relative velocity and relativistic binary collisions

Mirco Cannoni

摘要:

本文综述了在高能物理文献中经常被误解或未知的洛伦兹不变相对速度的概念。相对速度的性质允许公式化不变通量和横截面,而无需重复非物理速度或关于参考系的任何假设。应用,如对撞机的光度,作为运动学变量的使用,以及在相对论经典气体碰撞的统计理论进行了审查。它强调如何双曲线的速度空间的属性解释相对论散射的特点。

英文摘要:

This article reviews the concept of Lorentz invariant relative velocity that is often misunderstood or unknown in high energy physics literature. The properties of the relative velocity allow to formulate the invariant flux and cross section without recurring to non--physical velocities or any assumption about the reference frame. Applications such as the luminosity of a collider, the use as kinematic variable, and the statistical theory of collisions in a relativistic classical gas are reviewed. It is emphasized how the hyperbolic properties of the velocity space explain the peculiarities of relativistic scattering.
