夸克能量损失的一种新机制

A New Mechanism of Quark Energy Loss

Jorge Casalderrey-Solana, Daniel Fernandez, David Mateos

摘要:

我们证明了在夸克-胶子等离子体中运动足够快的重夸克可能会被切伦科夫辐射的介子损失能量。我们证明,这发生在所有强耦合,大NC等离子体与重力对偶。尽管是O(1/Nc)效应,但在这些模型中能量损失是可精确计算的。我们讨论了重离子碰撞实验的唯象意义。

英文摘要:

We show that a heavy quark moving sufficiently fast through a quark-gluon plasma may lose energy by Cherenkov-radiating mesons. We demonstrate that this takes place in all strongly coupled, large-Nc plasmas with a gravity dual. The energy loss is exactly calculable in these models despite being an O(1/Nc)-effect. We discuss phenomenological implications for heavy-ion collision experiments.
