集体效应强子产生中平均横动量的能量依赖性

Energy dependence of average transverse momentum in hadron production due to collective effects

S. M. Troshin, N. E. Tyurin

摘要:

受LHC实验CMS在$\sqrt{s}=0.9$和2.36 TeV的首次测量的启发,我们讨论了pp碰撞中强子产生中次级粒子平均横动量的能量依赖性.我们提出了一个可能的解释,这种依赖性作为集体旋转的瞬态的结果,并将其进一步可能的减少与平坦化在更高的能量与过渡到真正的QGP状态的物质。

英文摘要:

Motivated by the first measurements of the experiment CMS at the LHC at $\sqrt{s}=0.9$ and 2.36 TeV, we discuss energy dependence of average transverse momentum of the secondary particles in hadron production in pp collisions. We suggest a possible explanation of this dependence as a result of collective rotation of the transient state and associate its further possible decrease with flattening off at higher energies with transition to the genuine QGP state of matter.
