Combined SMEFT interpretation of Higgs, diboson, and top quark data from the LHC
Jacob J. Ethier, Giacomo Magni, Fabio Maltoni +6
We present a global interpretation of Higgs, diboson, and top quark production and decay measurements from the LHC in the framework of the Standard Model Effective Field Theory (SM…
Positivity in Multi-Field EFTs
Xu Li, Hao Xu, Chengjie Yang +2
We discuss the general method for obtaining full positivity bounds on multi-field effective field theories (EFTs). While the leading order forward positivity bounds are commonly de…
Generalized elastic positivity bounds on interacting massive spin-2 theories
Zi-Yue Wang, Cen Zhang, Shuang-Yong Zhou
We use generalized elastic positivity bounds to constrain the parameter space of multi-field spin-2 effective field theories. These generalized bounds involve inelastic scattering…
Elastic positivity vs extremal positivity bounds in SMEFT: a case study in transversal electroweak gauge-boson scatterings
Kimiko Yamashita, Cen Zhang, Shuang-Yong Zhou
The positivity bounds, derived from the axiomatic principles of quantum field theory (QFT), constrain the signs of Wilson coefficients and their linear combinations in the Standard…
Positivity in electron-positron scattering: testing the axiomatic quantum field theory principles and probing the existence of UV states
Benjamin Fuks, Yiming Liu, Cen Zhang +1
We consider the positivity bounds on dimension-8 four-electron operators and study two related phenomenological aspects at future lepton colliders. First, if positivity is violated…
Convex Geometry Perspective to the (Standard Model) Effective Field Theory Space
Cen Zhang, Shuang-Yong Zhou
We present a convex geometry perspective to the Effective Field Theory (EFT) parameter space. We show that the second derivatives of the forward EFT amplitudes form a convex co…
