An open problem in theoretical physics is to combine all four of the fundamental forces of nature into one singular theory. Problematically, gravity has proven difficult to reconcile with the other forces. Recently, relationships between scattering amplitudes in non-abelian gauge theories and theories of quantum gravity have led to the discovery of a relation known as the double copy. The...
The Cosmological Scattering Equations lead to a natural formulation of EFT wavefunction coefficients in de Sitter written in terms of conformal generators in the future boundary. The corresponding integrands can be assembled from simple building blocks (including mass deformations and curvature corrections) leading to a double copy prescription. We can also analyse the operator form of the...
The discrepancy between observations, and Standard Model (SM) predictions of the Baryon Asymmetry of the Universe implies the existence of physics beyond the SM, which must include further sources of CP violation- in general with O(1) phases. LHCb has recently made several CP asymmetry measurements for B->DD decays. For such non-leptonic modes, lack of knowledge of long-distance strong...
High Energy Jets (HEJ) is a resummation framework designed to include contributions from high energy logarithms in 𝑠̂ /𝑝2⊥ to all orders in perturbation theory. These logs can become significant at the LHC and future colliders, and are significantly enhanced by the requirement of a large dijet invariant mass or large rapidity separation common in VBF/VBS cuts.
I will present a poster giving...
Dark Matter has eluded us for decades and continues to do so. Current lepton colliders are currently being used to set exclusion limits on coupling constants and masses of various dark matter models, but many models would have either identical or too close to distinguish signals in a detector. There is hence a need for methods/observables to separate the signals. We look into whether measuring...
