Unitary Dual-Resonance S-matrices
Claudia de Rham, Andrew J. Tolley, Zhuo-Hui Wang +1
Dual-resonance models realize crossing symmetry, Regge behavior and infinitely many resonances in a compact analytic form but their canonical tree-level realizations fall short of…
S-matrix bootstrap bounds on self-interacting dark matter
Qing Chen, Zhuo-Hui Wang, Shuang-Yong Zhou
Self-interacting dark matter turns the structure of galactic halos into a direct requirement on a low-energy scattering amplitude. We show that, for weakly coupled scalar dark matt…
Effective Theory for Light Portal Dark Matter Detection
Qing Chen, Shuang-Yong Zhou
We develop a general framework for the computation of light portal dark matter direct detection, incorporating a consistent treatment of finite momentum transfer. In this framework…
Primal S-matrix bootstrap with dispersion relations
Claudia de Rham, Andrew J. Tolley, Zhuo-Hui Wang +1
We propose a new method for constructing the consistent space of scattering amplitudes by parameterizing the imaginary parts of partial waves and utilizing dispersion relations, cr…
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…
Bi-gravity Portal Dark Matter
Qing Chen, Shuang-Yong Zhou
We consider a model where the interaction between dark matter and the Standard Model particles are mediated by a ghost-free bi-gravity portal. The bi-gravity model invokes a massiv…
Capping the positivity cone: dimension-8 Higgs operators in the SMEFT
Qing Chen, Ken Mimasu, Tong Arthur Wu +2
SMEFT Wilson coefficients are subject to various positivity bounds in order to be consistent with the fundamental principles of S-matrix. Previous bounds on dimension-8 SMEFT opera…
