摘要
En 中文
We study the classical color radiation from very high energy collisions that produce colored particles. In the extreme high energy limit, the classical color fields are con fined to a light-shell expanding at c and are associated with a non-linear sigma-model on the 2D light-shell with specific symmetry breaking terms. We argue that the quantum version of this picture exhibits asymptotic freedom and may be a useful starting point for an effective light-shell theory of the structure between the jets at a very high energy collider.
