论文摘要
相对论重型离子碰撞（HIC）中的喷气机与夸克 - 胶状等离子体（QGP）相互作用，从而导致诸如抑制射流产量的效果和用于测量QGP特性的内部喷射结构的修饰。这些程序表明，在$ \ sqrt {s _ {\ rm nn}} $ = 5.02 TEV的各种中心性类别中，PB-PB碰撞中的包含喷气核修饰因子与Alice detector录制的分辨率参数最高为$ r $ = 0.6，tev devev cob = 0.6，tev均记录下来，达到40 GEV/$ C $。该分析利用机器学习技术来纠正HIC的较大背景，从而将包容性喷气机的测量扩展到降低JET $ P_ {T} $和更大的$ R $，而不是LHC的HICS。还将提出一套新的测量套件，以中央和半末端PB-PB碰撞中的软滴和动态美容算法同时表征修饰的喷射分裂。修饰的喷气半径，$θ_ {\ rm g} \ equiv r _ {\ rm g}/r $，修饰的喷气动量分数，$ z {\ rm g} $，以及修饰拆分的横向动量，$ k _ {\ rm tm t，也报告了。通过展开并将所有测量结果与各种理论计算进行完全纠正。
Jets in relativistic heavy-ion collisions (HICs) interact with the quark-gluon plasma (QGP), leading to effects such as a suppression of jet yields and a modification of internal jet structure that are used to measure the properties of the QGP. These proceedings show the inclusive jet nuclear modification factors in Pb--Pb collisions in various centrality classes at $\sqrt{s_{\rm NN}}$ = 5.02 TeV recorded with the ALICE detector for resolution parameters up to $R$ = 0.6 for momenta down to 40 GeV/$c$. The analysis utilizes machine learning techniques to correct the large background in HICs, extending the measurement of inclusive jets to lower jet $p_{T}$ and larger $R$ than previously achieved in HICs at the LHC. A new suite of measurements characterizing groomed jet splittings using both the Soft Drop and Dynamical Grooming algorithms in central and semi-central Pb--Pb collisions will also be presented. The groomed jet radius, $θ_{\rm g}\equiv R_{\rm g}/R$, the groomed jet momentum fraction, $z_{\rm g}$, and the transverse momentum of the groomed splitting, $k_{\rm T, g}$ are also reported. All measurements are fully corrected through unfolding and compared to various theoretical calculations.
