用JEWEL模拟重离子碰撞中的V+喷注过程

Simulating V+jet processes in heavy ion collisions with JEWEL

Raghav Kunnawalkam Elayavalli, Korinna Christine Zapp

摘要:

喷流反冲电弱玻色子的过程补充了大型强子对撞机重离子碰撞中喷流淬灭的研究。由于玻色子没有强烈的相互作用,它逃脱了致密介质未修改,从而提供了一个更直接的访问硬散射运动学比可以在di-jet事件。在这些过程中的喷流修正的第一次测量现在可以从大型强子对撞机实验,并将大大改善与更好的统计数据在未来。本文将JEWEL推广到玻色子喷注过程。JEWEL是一个基于微扰QCD的稠密背景中喷流演化的动力学框架,它与大量的喷流观测值相一致。我们还得到了一个很好的描述CMS和ATLAS数据的y+喷流和Z+喷流过程在2.76 TeV和5.02 TeV。

英文摘要:

Processes in which a jet recoils against an electroweak boson complement studies of jet quenching in heavy ion collisions at the LHC. As the boson does not interact strongly it escapes the dense medium unmodified and thus provides a more direct access to the hard scattering kinematics than can be obtained in di-jet events. First measurements of jet modification in these processes are now available from the LHC experiments and will improve greatly with better statistics in the future. We present an extension of JEWEL to boson-jet processes. JEWEL is a dynamical framework for jet evolution in a dense background based on perturbative QCD, that is in agreement with a large variety of jet observables. We also obtain a good description of the CMS and ATLAS data for y+jet and Z+jet processes at 2.76 TeV and 5.02 TeV.
