On Amplitudes and Field Redefinitions / Cohen, Timothy (CERN ; EPFL, Lausanne, LPTP ; Oregon U.) ; Lu, Xiaochuan (UC, San Diego) ; Sutherland, Dave (Glasgow U.)
We derive an off-shell recursion relation for correlators that holds at all loop orders. This allows us to prove how generalized amplitudes transform under generic field redefinitions, starting from an assumed behavior of the one-particle-irreducible effective action. [...]

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. [...]

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. [...]

The muon Smasher’s guide / Al Ali, Hind (UC, Santa Barbara) ; Arkani-Hamed, Nima (Princeton, Inst. 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. [...]
