论文摘要
我们对大型强子对撞机（LHC）的PB+PB碰撞中的W+Jets产生进行了详细的计算。在我们的计算中，P+P参考中W+JET的生产是从Sherpa获得的，Sherpa将其匹配到临时领先的矩阵元素与Parton淋浴计算的重新召集。线性玻尔兹曼传输（LBT）模型模拟了夸克 - 胶质等离子体中的射流传播和中等响应。我们计算PB+PB碰撞中具有喷射淬火效果的W+JET的五个可观察到的可观察到的事件分布作为Lepton和Jets $ | \ vec {p} _t} _t^{MISS} | $，标记的Jet Cross $ i_ {aa} $的核效应的核效果不平衡$ \ langle x_ {jw} \ rangle $，平均每w boson $ r_ {jw} $的喷气机数。讨论了这5种可观察到的核修饰，这是由于Pb+Pb中与P+P碰撞中的射流淬灭引起的。
We carry out a detailed calculations of W+jets production in Pb+Pb collisions at the Large Hadron Collider (LHC). In our calculations, the production of W+jet in p+p reference is obtained from Sherpa, which matches next-to-leading-order matrix elements to the resummation of parton shower calculations. Jet propagation and medium response in the quark-gluon plasma is simulated with the Linear Boltzmann Transport (LBT) model. We calculate five observables of W+jets productions with jet quenching effect in Pb+Pb collisions: event distribution as a function of the vector sum of the lepton and jets $|\vec{p}_T^{Miss}|$, nuclear effects for tagged jet cross sections $I_{AA}$, azimuthal angle correlations $Δϕ_{jW}$, mean value of momentum imbalance $\langle x_{jW}\rangle$, average number of jets per W boson $R_{jW}$. The nuclear modifications of these 5 observables due to jet quenching in Pb+Pb relative to that in p+p collisions are discussed.
