Research Motivation and Summary:
The Large Hadron Collider (LHC) is hunting for signs of New Physics (NP) in the vast amount of data collected by its experiments. If new states are heavier than the collider energy reach, their presence can be revealed by modifications of the interactions of the known particles. The Standard Model Effective Field Theory (SMEFT) parametrises such deviations from the SM, extending the sensitivity to scales beyond those directly probed at colliders. Determining the parameters of the EFT will shed light on the nature of NP and will provide hints to the most important questions in particle physics, such as the shape of the Higgs potential, its relation to electroweak baryogenesis and the amount of CP-violation and its connection to the matter-anti-matter asymmetry. A dedicated campaign of measurements and their SMEFT interpretation is a major goal of the LHC and requires coordination between experimentalists and theorists.
My research aims to provide beyond the state-of-the-art theoretical contributions to the SMEFT programme by:
1) Providing the first fully generic next-to-leading order Monte Carlo implementation of SMEFT operators, to allow theorists and experimentalists to perform realistic simulations and exploring the potential impact of two-loop corrections in various observables.
2) Combining accurate SMEFT predictions with LHC data to constrain the operators through a novel robust global determination. The findings, particularly if different from the SM expectations, will point to the scale and nature of NP. Assess the physics potential of proposed future colliders through projection studies.
3) Exploring new challenging ideas, such as i) the impact of operator running and mixing and ii) the optimisation of ways of extracting the Higgs self-coupling and probing CP-violation at the LHC and future colliders, two topics with profound implications for our theoretical understanding of particle physics.
