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…
DAMA/LIBRA and dark matter: decisive tension or contrived cancellation
Giorgio Busoni, Jonathan M. Cornell, Will Handley +6
The ANAIS-112 and COSINE-100 experiments were constructed to test the long-observed dark matter-like annual modulation signal reported by DAMA. While they have reported null result…
Analytic formulae for non-local magic in bipartite systems of qutrits and ququints
Giorgio Busoni, John Gargalionis, Ewan N. V. Wallace +1
We conjecture analytic expressions for the non-local magic of bipartite pure qudit states of prime local dimension. Our construction relies on the Schmidt-aligned state attaining t…
Emergent symmetry in a two-Higgs-doublet model from quantum information and nonstabiliserness
Giorgio Busoni, John Gargalionis, Ewan N. V. Wallace +1
Studies of scattering processes in scalar models with two Higgs doublets have recently hinted at a connection between the absence of flavour-space entanglement in scatte…
