QED positivity bounds
Lasma Alberte, Claudia de Rham, Sumer Jaitly +1
We apply positivity bounds directly to a gauge theory with charged scalars and charged fermions, i.e. QED, minimally coupled to gravity. Assuming that the massless -chann…

Positivity Bounds and the Massless Spin-2 Pole
Lasma Alberte, Claudia de Rham, Sumer Jaitly +1
The presence of a massless spin-2 field in an effective field theory results in a -channel pole in the scattering amplitudes that precludes the application of standard positivit…

Spontaneously broken boosts and the Goldstone continuum
Lasma Alberte, Alberto Nicolis
The spontaneous breaking of boost invariance is ubiquitous in nature, yet the associated Goldstone bosons are nowhere to be seen. We discuss why some subtleties are to be expected…
