BAO vs. SN evidence for evolving dark energy
Alessio Notari, Michele Redi, Andrea Tesi
We critically review the evidence for time-varying dark energy from recent Baryon Acoustic Oscillations (BAO) and Supernova (SN) observations. First, we show that such evidence is…
Stochastic Dark Matter from Curvature Perturbations
Raghuveer Garani, Michele Redi, Andrea Tesi
We investigate the production of dark matter from curvature perturbations produced during inflation or in standard cosmology, for example during first order phase transitions. Pert…
Large CP violation in flavor violating muon decays
Diego Redigolo, Michele Tammaro, Andrea Tesi
We identify new room for CP violation in lepton flavor violating observables not bound by the electric dipole moment of leptons. By focusing on new physics in the muon-electron sec…
Irreducible cosmological backgrounds of a real scalar with a broken symmetry
Francesco D'Eramo, Andrea Tesi, Ville Vaskonen
We explore the irreducible cosmological implications of a singlet real scalar field. Our focus is on theories with an approximate and spontaneously broken symmetry w…
Complex Dark Photon Dark Matter EFT
Enrico Bertuzzo, Tommaso Sassi, Andrea Tesi
We construct an effective field theory for complex Stueckelberg dark photon dark matter. Such an effective construction can be realized by writing down a complete set of operators…
Consistent Theories for the DESI dark energy fit
Alessio Notari, Michele Redi, Andrea Tesi
We search for physically consistent realizations of evolving dark energy suggested by the cosmological fit of DESI, Planck and Supernovae data. First we note that any lagrangian de…
