SMEFTs living on the edge: determining the UV theories from positivity and extremality
Cen Zhang
We study the "inverse problem" in the context of the Standard Model Effective Field Theory (SMEFT): how and to what extend can one reconstruct the UV theory, given the measured val…
Triple crossing positivity bounds for multi-field theories
Zong-Zhe Du, Cen Zhang, Shuang-Yong Zhou
We develop a formalism to extract triple crossing symmetric positivity bounds for effective field theories with multiple degrees of freedom, by making use of symmetric dispers…
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…
