Multipositivity Constrains the Chiral Lagrangian
Clifford Cheung, Jaehoon Jeong, Pyungwon Ko +3
The chiral Lagrangian is a cornerstone of modern particle physics, offering a systematic and quantitative description of low-energy pions. Using tools from the modern scattering am…
Causal Bounds on EFTs with anomalies with a Pseudoscalar, Photons, and Gravitons
Ziyu Dong, Jaehoon Jeong, Alex Pomarol
Theories with pseudoscalars that couple through anomalies (such as axion models) are of particular phenomenological interest. We carry out a comprehensive analysis of all bounds ob…
(Super)Gravity from Positivity
Brando Bellazzini, Alex Pomarol, Marcello Romano +1
We investigate whether the effective theory for isolated, massive, and weakly interacting spin- particles is compatible with causality and unitarity-i.e., the positivity of sc…
Bootstrapping the Chiral-Gravitational Anomaly
Zi-Yu Dong, Teng Ma, Alex Pomarol +1
We analyze causality and unitarity constraints in graviton scattering amplitudes, aiming to establish new bounds on theories with -gravitational anomalies, such as axion mode…
Nonthermal Heavy Dark Matter from a First-Order Phase Transition
Gian F. Giudice, Hyun Min Lee, Alex Pomarol +1
We study nonthermal production of heavy dark matter from the dynamics of the background scalar field during a first-order phase transition, predominantly from bubble collisions. In…
Exploring the conformal transition from above and below
Alex Pomarol, Lindber Salas
We consider conformal transitions arising from the merging of IR and UV fixed points, expected to occur in QCD with a large enough number of flavors. We study the smoothness of phy…
