论文摘要
电动混合角是电子相互作用理论的基本参数。它的值已通过$ \ mathrm {z} $ - colliders的杆精确地测量。在这项贡献中，我们建议利用大型强大的强大强化群体中中性电流的Drell-Yan产生的测量，以确定$ \ bar {\ bar {\ text {ms}}} $ renormalisation $ renormalisation $ renormalisation $ renormalisation $ renormalisation $ renormalisation $ renormalisation $ renormalisation $ renormalisation $ renormalisation $ renormalisation $ renormalisation $ renormalisation $ $ \ sin^2θ_{w，\ ell}^{\ bar {\ text {ms}}}}}（μ）$。这样的测量可用于确认以$ \ bar {\ text {ms}} $在$ \ text {tev} $ scales运行的标准模型预测，并在具有电动量量子数字的新状态上设置模型无关的约束。为此，我们利用$ \ sin^2θ_{w，\ ell}^{\ bar {\ bar {\ bar {\ text {ms}}}}（μ）$ $在powheg-box-v2 monte carlo事件生成器中的$，我们用来探索未来分析的潜在分析的潜在分析，以探索LHC运行3和lhc rumin的潜在。
The electroweak mixing angle is a fundamental parameter of the theory of electroweak interactions. Its value has been measured precisely at the $\mathrm{Z}$-pole at colliders. In this contribution, we propose to exploit measurements of Neutral-Current Drell-Yan production at the Large Hadron Collider at large invariant dilepton masses to determine the energy scale dependence (running) of the electroweak mixing angle in the $\bar{\text{MS}}$ renormalisation scheme, $\sin^2θ_{W,\ell}^{\bar{\text{MS}}}(μ)$. Such a measurement can be used to confirm the Standard Model predictions for the $\bar{\text{MS}}$ running at $\text{TeV}$ scales, and to set model-independent constraints on new states with electroweak quantum numbers. To this end, we make use of a dedicated implementation of $\sin^2θ_{W,\ell}^{\bar{\text{MS}}}(μ)$ in the POWHEG-BOX-V2 Monte Carlo event generator, which we use to explore the potential of future analyses using the data of the LHC Run 3 and High-Luminosity.
