相对论性重离子碰撞中的横向动量流关联

Transverse momentum-flow correlations in relativistic heavy-ion collisions

Piotr Bozek

摘要:

研究了横向动量与流动的方位不对称性之间的关系.在事件中发射的强子的平均横向动量与椭圆流或三角流系数的平方之间定义了相关系数。流体动力学模型预测的正相关的横向动量与椭圆流,几乎没有相关性的铅铅碰撞在LHC能量的三角流。在p-Pb碰撞中,新的关联观测对碰撞第一阶段的能量沉积机制非常敏感。

英文摘要:

The correlation between the transverse momentum and the azimuthal asymmetry the flow is studied. A correlation coefficient is defined between the average transverse momentum of hadrons emitted in an event and the square of the elliptic or triangular flow coefficient. The hydrodynamic model predicts a positive correlation of the transverse momentum with the elliptic flow, and almost no correlation with the triangular flow in Pb-Pb collisions at LHC energies. In p-Pb collisions the new correlation observable is very sensitive to the mechanism of energy deposition in the first stage of the collision.
