强子与核碰撞中的玻色-爱因斯坦关联和$\mathbf{v_{2n}}$和$\mathbf{v_{2n-1}}$

Bose-Einstein correlations and $\mathbf{v_{2n}}$ and $\mathbf{v_{2n-1}}$ in hadron and nucleus collisions

E. Gotsman, E. Levin, U. Maor

摘要:

我们证明了强子与核高能碰撞中全同粒子的玻色-爱因斯坦关联导致了方位角上的长程快度关联。这些相关性是CGC/饱和方法的固有特征,然而,它们的起源比这种方法更普遍。在所提出的技术的框架中,偶数和奇数$v_n$都自然发生,与目标和射弹的类型无关。我们认为,现在就断定方位角关联的出现是由于夸克-胶子等离子体的流体力学行为是不成熟的。

英文摘要:

We show that Bose-Einstein correlations of identical particles in hadron and nucleus high energy collisions, lead to long range rapidity correlations in the azimuthal angle. These correlations are inherent features of the CGC/saturation approach, however, their origin is more general than this approach. In framework of the proposed technique both even and odd $v_n$ occur naturally, independent of the type of target and projectile. We are of the opinion that it is premature to conclude that the appearance of azimuthal correlations are due to the hydrodynamical behaviour of the quark-gluon plasma.
