Effective Field Theory of the Two Higgs Doublet Model
/ Banta, Ian (UC, Santa Barbara) ; Cohen, Timothy (CERN ; EPFL, Lausanne, LPTP ; Oregon U.) ; Craig, Nathaniel (UC, Santa Barbara ; Santa Barbara, KITP) ; Lu, Xiaochuan (UC, San Diego) ; Sutherland, Dave (Glasgow U.)
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 the effective description that resum important contributions from the Higgs vacuum expectation value. [...]

A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. [...]

On-Shell Covariance of Quantum Field Theory Amplitudes
/ Cohen, Timothy (Oregon U.) ; Craig, Nathaniel (UC, Santa Barbara) ; Lu, Xiaochuan (Oregon U.) ; Sutherland, Dave (INFN, Trieste ; CERN)
Scattering amplitudes in quantum field theory are independent of the field parameterization, which has a natural geometric interpretation as a form of `coordinate invariance.' Amplitudes can be expressed in terms of Riemannian curvature tensors, which makes the covariance of amplitudes under non-derivative field redefinitions manifest. We present a generalized geometric framework that extends this manifest covariance to $all$ allowed field redefinitions. [...]

Advanced Study) ; Banta, Ian (UC, Santa Barbara) ; Benevedes, Sean (UC, Santa Barbara) ; Buttazzo, Dario (INFN, Pisa) ; Cai, Tianji (UC, Santa Barbara) ; Cheng, Junyi (UC, Santa Barbara) ; Cohen, Timothy (Oregon U.) ; Craig, Nathaniel (UC, Santa Barbara) ; Ekhterachian, Majid (Maryland U.) et al.
We lay out a comprehensive physics case for a future high-energy muon collider, exploring a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the advantages of such a collider over proposed alternatives. [...]
