Ivan Vitev

摘要:

综述了稠密核物质中部分子非弹性相互作用的多体微扰QCD理论和重离子碰撞中强相互作用硬探针唯象的最新进展。我们强调的进展,已经取得了一致的辐射和碰撞能量损失之间的比较,探索新的重味抑制机制的夸克-胶子等离子体,并确定冷核物质的阻止功率。在大型强子对撞机前所未有的高质量质心的能量,使未来的方向和机会,在核碰撞射流物理,也进行了讨论。我们建议,射流形状的物理学和概括的QGP中的包容性粒子抑制将提供一个新的差分,并准确测试的基础QCD理论和一个新的精确工具,在大型强子对撞机射流层析成像。

英文摘要:

Recent developments in the many-body perturbative QCD theory of inelastic parton interactions in dense nuclear matter and the phenomenology of strongly-interacting hard probes in heavy ion collisions are reviewed. We highlight the progress that has been made toward consistent comparison between radiative and collisional energy loss, the exploration of novel heavy flavor suppression mechanisms in the quark-gluon plasma, and the determination of the stopping power of cold nuclear matter. Future directions and opportunities for jet physics in nuclear collisions, enabled by the unprecedentedly high center of mass energies at the LHC, are also discussed. We propose that the physics of jet shapes and a generalizations of the well-understood inclusive particle suppression in the QGP will provide a new differential, and accurate test of the underlying QCD theory and a new precision tool for jet tomography at the LHC.
