BSM patterns in scalar-sector coupling modifiers
Christoph Englert, Wrishik Naskar, Dave Sutherland
We consider what multiple Higgs interactions may yet reveal about the scalar sector. We estimate the sensitivity of a Feynman topology-templated analysis of weak boson Higgs pair p…
Effective Field Theories as Lagrange Spaces
Nathaniel Craig, Yu-Tse Lee, Xiaochuan Lu +1
We present a formulation of scalar effective field theories in terms of the geometry of Lagrange spaces. The horizontal geometry of the Lagrange space generalizes the Riemannian ge…
Effective Field Theory of the Two Higgs Doublet Model
Ian Banta, Timothy Cohen, Nathaniel Craig +2
We revisit the effective field theory of the two Higgs doublet model at tree level. The introduction of a novel basis in the UV theory allows us to derive matching coefficients in…
Building blocks of the flavourful SMEFT RG
Camila S. Machado, Sophie Renner, Dave Sutherland
A powerful aspect of effective field theories is connecting scales through renormalisation group (RG) flow. The anomalous dimension matrix of the Standard Model Effective Field The…
On-Shell Covariance of Quantum Field Theory Amplitudes
Timothy Cohen, Nathaniel Craig, Xiaochuan Lu +1
Scattering amplitudes in quantum field theory are independent of the field parameterization, which has a natural geometric interpretation as a form of `coordinate invariance.' Ampl…
Non-Decoupling New Particles
Ian Banta, Timothy Cohen, Nathaniel Craig +2
We initiate the study of a new class of beyond the Standard Model states that we call "Loryons." They have the defining characteristic of being non-decoupling, in the sense that th…
