硬部分子动量沉积引起的流动各向异性

Flow anisotropies due to momentum deposition from hard partons

Boris Tomasik, Martin Schulc

摘要:

在大型强子对撞机的核碰撞中,大量的硬部分子是在初始的部分子相互作用中产生的,因此可以合理地假设它们不会立即热化,而是将它们的能量和动量储存在演化中的热夸克-胶子流体中。我们表明,这种机制导致在所有订单的流量各向异性的贡献是不可忽略的,应该考虑在现实的模拟。

英文摘要:

In nuclear collisions at the LHC large number of hard partons are created in initial partonic interactions, so that it is reasonable to suppose that they do not thermalise immediately but deposit their energy and momentum later into the evolving hot quark-gluon fluid. We show that this mechanism leads to contribution to flow anisotropies at all orders which are non-negligible and should be taken into account in realistic simulations.
