I. P. Lokhtin, A. A. Alkin, A. M. Snigirev

摘要:

在PYQUEN喷注猝灭模型的框架下,分析和解释了质心能量为2.76TeV/核子对的PbPb碰撞中喷注碎裂函数和喷注形状的LHC数据.一个具体的修改纵向和径向射流轮廓在大多数中央PbPb碰撞相比,PP数据是接近与PYQUEN模拟考虑到广角辐射和碰撞部分子能量损失。辐射和碰撞损失的介质修改喷流内结构的贡献进行了估计。

英文摘要:

The LHC data on jet fragmentation function and jet shapes in PbPb collisions at center-of-mass energy 2.76 TeV per nucleon pair are analyzed and interpreted in the frameworks of PYQUEN jet quenching model. A specific modification of longitudinal and radial jet profiles in most central PbPb collisions as compared with pp data is close to that obtained with PYQUEN simulations taking into account wide-angle radiative and collisional partonic energy loss. The contribution of radiative and collisional loss to the medium-modified intra-jet structure is estimated.
