Effective Field Theory (EFT) is a model independent framework which allows us to search for heavy New Physics at the Large Hadron Collider. A lot of effort has been devoted towards improving theoretical predictions in the EFT to maximise our sensitivity to New Physics effects. The project aims to provide the first computation of electroweak corrections in the SMEFT, also implementing these in public tools to allow theorists and experimentalists to perform realistic simulations. Another goal is to combine accurate SMEFT predictions with LHC data to constrain the operators through a robust global determinations. The findings, particularly if different from the SM expectations, will point to the scale and nature of NP. Finally we aim to explore new challenging proposals, such as i) the impact of operator running and mixing on EFT interpretations and ii) the prospects of measuring quantum observables at the LHC.

有效场论（EFT）是一个模型独立的框架，它允许我们在大型强子对撞机上寻找重物理。大量的努力致力于改进EFT中的理论预测，以最大限度地提高我们对新物理效应的敏感性。该项目旨在提供SMEFT中的电弱校正的第一次计算，并在公共工具中实现这些，以允许理论家和实验学家进行逼真的模拟。另一个目标是将联合收割机精确的SMEFT预测与LHC数据结合起来，通过一个鲁棒的全局确定来约束操作员。研究结果，特别是如果不同于SM的期望，将指向NP的规模和性质。最后，我们的目标是探索新的具有挑战性的建议，如i）运营商运行和混合EFT解释的影响和ii）在大型强子对撞机测量量子可观测量的前景。
