On How Neutrino Protects the Axion
Gia Dvali, Sarah Folkerts, Andre Franca
We show how the neutrino can sacrifice itself to quantum gravity and save the axion solution to the strong-CP problem. This mechanism puts an upper bound on the lightest neutrino m…
Massive spin-2 theories
Sarah Folkerts, Cristiano Germani, Nico Wintergerst
We give an introduction to massive spin-2 theories and the problem of their non-linear completion. We review the Boulware-Deser ghost problem and two ways to circumvent classic no-…
Axion Dark Matter and Planck favor non-minimal couplings to gravity
Sarah Folkerts, Cristiano Germani, Javier Redondo
Constraints on inflationary scenarios and isocurvature perturbations have excluded the simplest and most generic models of dark matter based on QCD axions. Considering non-minimal…
