Positivity vs. Lorentz-violation: an explicit example
Katsuki Aoki, Shinji Mukohyama, Ryo Namba
We show how a class of multi-field scalar-field theories in a Lorentz-breaking background imposes consistency conditions on its effective theory of a single field and provides an e…
Is the Standard Model in the Swampland? Consistency Requirements from Gravitational Scattering
Katsuki Aoki, Tran Quang Loc, Toshifumi Noumi +1
We study compatibility of the Standard Model of particle physics and General Relativity by means of gravitational positivity bounds, which provide a necessary condition for a low-e…
Non-uniqueness of massless transverse-traceless graviton
Katsuki Aoki, Francesco Di Filippo, Shinji Mukohyama
We study a theory of minimally modified gravity called cuscuton/VCDM that propagates only two gravitational degrees of freedom. Despite being apparently different from general rela…
