We treat the Standard Model as the low-energy limit of an effective field theory that incorporates higher-dimensional operators to capture the effects of decoupled new physics. We consider theâ€¦ (More)

In a recent paper, Cho, Kim and Yoon (CKY) have proposed a version of the SU(2) Ã— U(1) Standard Model with finite-energy monopole and dyon solutions. The CKY model postulates that the effective U(1)â€¦ (More)

We explore the indirect sensitivities to decoupled new physics of prospective precision electroweak measurements, triple-gauge-coupling measurements and Higgs physics at future e+eâˆ’ colliders, withâ€¦ (More)

We develop a universal approach to the one-loop effective field theory (EFT) using the Covariant Derivative Expansion (CDE) method. We generalise previous results to include broader classes of UVâ€¦ (More)

Constraints on the full set of Standard Model dimension-6 operators have previously used triple-gauge couplings to complement the constraints obtainable from Higgs signal strengths. Here we extendâ€¦ (More)

We present the activities of the 'New Physics' working group for the 'Physics at TeV Colliders' workshop (Les Houches, France, 1-19 June, 2015). Our report includes new physics studies connected withâ€¦ (More)

The recent measurement by ATLAS of light-by-light scattering in LHC PbPb collisions is the first direct evidence for this basic process. We find that it excludes a range of the mass scale of aâ€¦ (More)

Recently, a general result for evaluating the path integral at one loop was obtained in the form of the Universal One-Loop Effective Action. It may be used to derive effective field theory operatorsâ€¦ (More)
