Sampling the Graviton Pole and Deprojecting the Swampland
Guangzhuo Peng, Laurentiu Rodina, Anna Tokareva +1
We develop a primal bootstrap framework for effective field theories in the presence of a graviton pole, based on finite-resolution sampling rather than smearing, while also allowi…
Weak Gravity Conjecture in the sky: gravitational waves from preheating in Einstein-Maxwell-Scalar EFT
Jiaxin Cheng, Anna Tokareva
The effective field theory (EFT) concept provides a necessary tool for obtaining general predictions of low-energy theory valid below its unitarity-breaking scale (cutoff scale). E…
Lectures in Quantum Gravity
Ivano Basile, Luca Buoninfante, Francesco Di Filippo +3
Formulating a quantum theory of gravity lies at the heart of fundamental theoretical physics. This collection of lecture notes encompasses a selection of topics that were covered i…
Scalar weak gravity bound from full unitarity
Anna Tokareva, Yongjun Xu
Weak gravity conjecture can be formulated as a statement that gravity must be the weakest force, compared to the other interactions in low energy effective field theory (EFT). Seve…
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…
