/Higgs inflation and the hierarchy problem
Pedro G. Ferreira, Christopher T. Hill, Johannes Noller +1
We analyse Starobinsky inflation in the presence of the Brout Englert Higgs (BEH) boson with a non-minimal coupling to the Ricci scalar, . The latter induces a coupling of the m…
On tachyonic stability priors for dark energy
Rafaela Gsponer, Johannes Noller
A number of stability criteria exist for dark energy theories, associated with requiring the absence of ghost, gradient and tachyonic instabilities. Tachyonic instabilities are the…
Theoretical priors in scalar-tensor cosmologies: Shift-symmetric Horndeski models
Dina Traykova, Emilio Bellini, Pedro G. Ferreira +3
Attempts at constraining theories of late time accelerated expansion often assume broad priors for the parameters in their phenomenological description. Focusing on shift-symmetric…
Positivity Bounds on Dark Energy: When Matter Matters
Claudia de Rham, Scott Melville, Johannes Noller
Positivity bounds - constraints on any low-energy effective field theory imposed by the fundamental axioms of unitarity, causality and locality in the UV - have recently been used…
