Gravitational positivity bounds
Junsei Tokuda, Katsuki Aoki, Shin'ichi Hirano
We study the validity of positivity bounds in the presence of a massless graviton, assuming the Regge behavior of the amplitude. Under this assumption, the problematic -channel…

Noise and decoherence induced by gravitons
Sugumi Kanno, Jiro Soda, Junsei Tokuda
We study quantum noise and decoherence induced by gravitons. We derive a Langevin equation of geodesic deviation in the presence of gravitons. The amplitude of noise correlations t…

Extension of positivity bounds to non-local theories: IR obstructions to Lorentz invariant UV completions
Junsei Tokuda
We derive positivity bounds on low energy effective field theories which admit gapped, analytic, unitary, Lorentz invariant, and possibly non-local UV completions, by considering 2…
