Large-Field Vacuum Decay in General Multi-Scalar Theories
Giorgio Busoni, Florian Goertz, Navneet Krishnan +1
Many theories beyond the standard model exhibit multiple scalar particles. Such multi-scalar theories can in principle host lower-energy vacua, and thus predict that our universe h…
The quantum criticality of the Standard Model and the hierarchy problem
Juan P. Garcés, Florian Goertz, Manfred Lindner +1
The naturalness principle has long guided efforts to understand physics beyond the Standard Model, with the hierarchy problem as the central issue. We revisit the role of quantum c…
Phasing out of Darkness: From Sterile Neutrino Dark Matter to Neutrino Masses via Time-Dependent Mixing
Florian Goertz, Maya Hager, Giorgio Laverda +1
Sterile neutrinos are a compelling candidate for generating neutrino masses and for elucidating the nature of dark matter. Astrophysical X-ray constraints on sterile neutrino dark…
Gauge-Fermion Cartography: from confinement and chiral symmetry breaking to conformality
Florian Goertz, Ãlvaro Pastor-Gutiérrez, Jan M. Pawlowski
We study, for the first time, the interplay between colour-confining and chiral symmetry-breaking dynamics in gauge-fermion systems with a general number of flavours and colours. S…
