The Large Hadron Collider (LHC) is transitioning from an initial exploratory phase to a long term data aggregation phase. A diverse set of Standard Model processes are being measured with increasing precision, across a wide range of energies and cross sections. The goal of this workshop is to explore precision measurements of Standard Model processes at the LHC as tools to search for new physics Beyond the Standard Model, with an emphasis on measurements that will benefit from the large increase in luminosity anticipated during Run 3 and the High Luminosity phases of the LHC. Processes to be studied include Higgs decays and kinematics, jets, top quark distributions, electroweak measurements, and high energy tails. Measurements of these processes can be exploited to constrain the Standard Model Effective Field theory and to search for new particles that are hidden beneath backgrounds. One key focus of the program will be to explore Machine Learning as a tool to extract maximum information from future LHC measurements.

This program aims to gather experts on Standard Model theory, including QCD and electroweak calculations, with experts on Beyond the Standard Model theory, to explore synergies between these topics. The program will also bring experts on Machine Learning and its application to collider physics. Together, these communities will chart physics goals for Run 3 and the High Luminosity phases of the LHC at the interface of Standard Model and Beyond Standard Model physics.
