"In the coming decades in high energy physics, we will see many big experiments generate big datasets, such as the revamped HL-LHC proton-proton collider, and the LIGO-Virgo-KAGRA collective of gravitational wave detectors. Our predictions for many of these experiments come from an underlying field theory, and its corresponding amplitudes that describe scattering processes.Common to these big experiments are two bottlenecks. One, there is a large number of possibilities for what we might see. Two, our analytical and numerical field theoretic predictions for each of these possibilities can take a long time to produce.This proposal aims to improve our search for new fundamental physics discoveries on both counts, including by:1. narrowing down the possibilities for what we might see in colliders, such as Belle II, the LHC and future colliders. This will involve a comprehensive survey of simplified models of new physics in the electroweak sector, calculating their current and projected constraints from Higgs, electroweak precision, and flavour data.2. extending functional and on-shell methods, such as constructability algorithms, to work with the numerous local interactions produced by heavy new particles in high energy experiments, as encoded by SMEFT or HEFT.3. applying the same to effective field theories relevant for numerical relativity calculations of gravitational waveforms to generate faster, more precise calculational techniques."

“在接下来的几十年中，在高能物理学中，我们将看到许多大型实验会产生大型数据集，例如改建后的HL-LHC Proton-Proton Collider和Ligo-Virgo-Kagra集体引力波探测器。我们对许多许多预测的预测这些实验来自一个基本的田间理论，其相应的幅度描述了散射过程。对这些大型实验的概括是两个瓶颈。这些可能性的预测可能需要很长时间才能生产。该提案旨在改善我们对这两种罪名的新基本物理发现的搜索，包括：1。 II，LHC和未来的山利区都将涉及对Electroweak行业中新物理学的简化模型的全面调查，从而计算其当前和预测的限制。扩展功能性和壳上的方法（例如可构算法算法）与高能量实验中重型新粒子产生的众多局部相互作用（由SMEFT或HEFT编码）。3。将其应用于与重力波形的数值相对性计算相关的有效场理论，以生成更快，更精确的计算技术。”
