基于几何数据的非微扰射流猝灭

Non-perturbative Jet Quenching from Geometric Data

Jinfeng Liao

摘要:

本文讨论了从RHIC到LHC能量的重离子碰撞中高能喷流穿透热QCD物质的几何层析成像。特别是高$p_t$强子方位各向异性的几何数据区分了不同的模型,并强烈暗示了能量损失机制超出了那些基于微扰理论。结合RHIC和LHC的实验数据,与模型的比较表明,在近$T_c$物质中喷注淬灭增强的模型是有利的。

英文摘要:

This contribution discusses the geometric tomography by highly energetic jets penetrating the hot QCD matter in heavy ion collisions from RHIC to LHC energies. In particular the geometric data on the azimuthal anisotropy of high $p_t$ hadrons discriminate different models and strongly hint at energy loss mechanism beyond those based on perturbation theory. Taking together the RHIC and LHC data, the comparison with models is in favor of the model with strong enhancement of jet quenching in near-$T_c$ matter.
