论文摘要
我们将drell-yan过程$ pp \ to \ ell \ ell \ ell \ ell \ el^{（\ prime）} $和$ pp \ to \ ell \barν$ at High-$ p_t $作为半蛋白质过渡中新物理效应的探针。为此，我们将$ 2 \ to2 $的散射幅度描述为一般的表单因子，我们以$ \ Mathcal {o}（1/λ^{4}）$匹配，包括尺寸 - $ 8 $运算符的校正 - 运算符，并从$ \ nathcal of \ natercal {tev）comportor contriension- $ 8 $ cliepention- $ 8 $（tev）$（tev）。通过使用来自Monolepton和Dilepton生产渠道的最新LHC Run-II数据，我们在SMEFT和Leptoquark模型上得出了限制，具有最通用的风味结构。我们的结果被编译到Mathematica软件包“ Highpt”中，该软件包提供了一种简单的方法，可以在标准模型之外执行Drell-Yan生产的高$ P_T $撞机分析。
We consider the Drell-Yan processes $pp \to \ell \ell^{(\prime)}$ and $pp\to \ell \barν$ at high-$p_T$ as probes of New Physics effects in semileptonic transitions. For this purpose, we describe the $2\to2$ scattering amplitudes in terms of general form-factors which we match to the SMEFT at $\mathcal{O}(1/Λ^{4})$ including corrections from dimension-$8$ operators and to tree-level mediators with $\mathcal{O}$(TeV) masses arising from ultraviolet models. By using the latest LHC run-II data from monolepton and dilepton production channels, we derive constraints on the SMEFT and on leptoquark models, with the most general flavor structures. Our results are compiled into the Mathematica package 'HighPT', which provides a simple way to perform high-$p_T$ collider analyses of Drell-Yan production Beyond the Standard Model.
