Running EFT-hedron with null constraints at loop level
Guangzhuo Peng, Long-Qi Shao, Anna Tokareva +1
Implications of general properties of quantum field theory, such as causality, unitarity, and locality include constraints on the couplings of the effective field theory (EFT) coef…

Non-local positivity bounds: islands in Terra Incognita
Luca Buoninfante, Long-Qi Shao, Anna Tokareva
The requirements of unitarity and causality lead to significant constraints on the Wilson coefficients of an EFT expansion, known as positivity bounds. Their standard derivation re…
