论文摘要
矢量玻色子的生产标记为重夸克喷气机可能提供了新的工具来探测喷射淬火效果。在本文中，我们介绍了有关角相关性（$ δϕ_ {bz} $），横向动量不平衡（$ x_ {bz} $）和核修饰因子（$ i_ {aa} $ $ z^0 $ z^0 $ boson boson b-jets in Regie-iros collisions of Monte carlo carlo carlo carlo carlo carlo carlo carlo carlo carlo carlo carlo b-jets。我们发现，$ δϕ_ {bz} $的介质修改对于$ z^0 \，+\，$ b-jet对$ δϕ_ {bz} $的依赖性较弱，而不是$ z^0 \，+\，$ jet，并且对初始jet $ p_t $ p_t $分布敏感。此外，随着Quark Jet在$ z^0 \，+\，$（b-）喷气生产中的高纯度，我们计算动量不平衡$ x_ {bz} $和核修饰因子$ i_ {aa} $ $ z^0 \，+\，+\，+\，$ b-jet，$ b-jet，$ b-jet，$ b-jet，$ b-jet在pb+pb colusions中。 We observe a smaller $Δ\left\langle x_{jZ} \right\rangle$ and larger $I_{AA}$ of $Z^0\,+\,$b-jet in Pb+Pb collisions relative to those of $Z^0\,+\,$jet, which may be an indication of the mass effect of jet quenching and can be tested in future measurements.
The production of vector boson tagged heavy quark jets potentially provides new tools to probe the jet quenching effect. In this paper, we present the first theoretical study on the angular correlations ($Δϕ_{bZ}$), transverse momentum imbalance ($x_{bZ}$), and nuclear modification factor ($I_{AA}$) of $Z^0$ boson tagged b-jets in heavy-ion collisions, which was performed using a Monte Carlo transport model. We find that the medium modification of the $Δϕ_{bZ}$ for $Z^0\,+\,$b-jet has a weaker dependence on $Δϕ_{bZ}$ than that for $Z^0\,+\,$jet, and the modification patterns are sensitive to the initial jet $p_T$ distribution. Additionally, with the high purity of the quark jet in $Z^0\,+\,$(b-)jet production, we calculate the momentum imbalance $x_{bZ}$ and the nuclear modification factor $I_{AA}$ of $Z^0\,+\,$b-jet in Pb+Pb collisions. We observe a smaller $Δ\left\langle x_{jZ} \right\rangle$ and larger $I_{AA}$ of $Z^0\,+\,$b-jet in Pb+Pb collisions relative to those of $Z^0\,+\,$jet, which may be an indication of the mass effect of jet quenching and can be tested in future measurements.
