基本和重离子碰撞中的幂律:涨落和非扩展性的故事?

Power laws in elementary and heavy-ion collisions - A story of fluctuations and nonextensivity?

Grzegorz Wilk, Zbigniew Wlodarczyk

摘要:

本文从非广延统计的观点出发,评述了幂律分布在基本碰撞和重离子碰撞中的普遍存在。特别强调的猜想,这只是一个反映了一些固有的波动存在于强子系统考虑。在基于Tsallis熵的非广延统计模型中,这些系统概括地用一个单一的参数q来描述,q起着非广延性度量的作用。

英文摘要:

We review from the point of view of nonextensive statistics the ubiquitous presence in elementary and heavy-ion collisions of power-law distributions. Special emphasis is placed on the conjecture that this is just a reflection of some intrinsic fluctuations existing in the hadronic systems considered. These systems summarily described by a single parameter q playing the role of a nonextensivity measure in the nonextensive statistical models based on Tsallis entropy.
