Positivity Bounds on parity-violating scalar-tensor EFTs
Hao Xu, Dong-Yu Hong, Zhuo-Hui Wang +1
Using dispersion relations of the scattering amplitudes and semi-definite programming, we calculate causality bounds on the Wilson coefficients in scalar-tensor effective field the…

On Capped Higgs Positivity Cone
Dong-Yu Hong, Zhuo-Hui Wang, Shuang-Yong Zhou
The Wilson coefficients of the Standard Model Effective Field Theory are subject to a series of positivity bounds. It has been shown that, while the positivity part of the UV parti…

Causality bounds on scalar-tensor EFTs
Dong-Yu Hong, Zhuo-Hui Wang, Shuang-Yong Zhou
We compute the causality/positivity bounds on the Wilson coefficients of scalar-tensor effective field theories. Two-sided bounds are obtained by extracting IR information from UV…
