QCD演化方程的混沌解能抑制高能对撞机物理吗?
Can a chaotic solution in the QCD evolution equation restrain high-energy collider physics?
摘要:
我们指出,在修正的Balisky-Fadin-Kuraev-Lipatov(BFKL)方程中,胶子分布的随机非周期振荡具有正的李雅普诺夫指数.这是QCD演化方程中的第一个混沌例子,它引起了胶子分布在Bjorken变量$x$的临界小值处的突然消失,并可能阻止超高能强子对撞机中新粒子事件的增加。
英文摘要:
We indicate that the random aperiodic oscillation of the gluon distributions in a modified Balisky--Fadin--Kuraev--Lipatov (BFKL) equation has positive Lyapunov exponents. This first example of chaos in QCD evolution equations, raises the sudden disappearance of the gluon distributions at a critical small value of the Bjorken variable $x$ and may stop the increase of the new particle events in an ultra high energy hadron collider.
