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…
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…
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…
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…
