LHC Pb+Pb碰撞中介质中喷注簇射演化和双喷注不对称性

Jet shower evolution in medium and dijet asymmetry in Pb+Pb collisions at the LHC

摘要:

研究了部分子喷流簇射在夸克-胶子等离子体中的演化。结合主导部分子和簇射胶子在介质中的演化,我们计算了通过与介质组分的弹性碰撞耗散、簇射部分子向较大角度的散射以及喷流锥外的辐射对喷流锥能量的消耗。本文给出了在LHC上Pb+Pb碰撞中双喷流不对称性的核修正的数值结果。

英文摘要:

We study the evolution of a partonic jet shower propagating through a quark-gluon plasma. Combining the in-medium evolutions of the leading parton and shower gluons, we compute the depletion of the energy from the jet cone by dissipation through elastic collisions with medium constituents, by scattering of shower partons to larger angles, and by radiation outside the jet cone. Numerical results are presented for the nuclear modification of dijet asymmetry in Pb+Pb collisions at the LHC.
