摘要
在这项工作中,我们首次研究了重离子对撞中的射流-介质相互作用,并引入了饱和效应和苏达科夫效应,其参数是根据即将进行的前向量热器接受实验,特别是 ALICE FoCal 探测器而调整的。我们利用描述喷流与夸克-胶子等离子体(QGP)相互作用的 BDIM 方程,结合类真空发射(VLE),考虑了中间粒子演化,重点研究了 $\gamma +$jet 相关性。我们通过小-$x$改进横动量相关因式分解(ITMD)系统地引入了早期胶子饱和动力学。为此,我们使用蒙特卡洛程序KATIE和TMDICE分别生成硬事件和中子演化。我们给出了方位相关性和核调制比的结果,以衡量胶子饱和效应在中子喷流能量损失早期时间的影响。
Predictions for photon-jet correlations at forward rapidities in heavy-ion collisions
In this work, we study for the first time jet-medium interactions in
heavy-ion collisions with introduction of saturation and Sudakov effects with
parameters tuned for upcoming forward calorimeter acceptances in experiments,
in particular the ALICE FoCal detector. We focus on $\gamma +$jet correlations
by taking into account in-medium parton evolution using the BDIM equation that
describes jet interactions with the quark-gluon plasma (QGP) combined with
vacuum-like emissions (VLE). We systematically introduce the early time gluon
saturation dynamics through the small-$x$ Improved Transverse Momentum
Dependent factorization (ITMD). For our purpose, we use Monte Carlo programs
KATIE and TMDICE to generate hard events and in-medium parton evolution,
respectively. We present results of azimuthal correlations and nuclear
modification ratios to gauge the impact of the gluon saturation effects at
early time for the in-medium jet energy loss.
