The number density of a charged relic
Carola F. Berger, Laura Covi, Sabine Kraml +1
We investigate scenarios in which a charged, long-lived scalar particle decouples from the primordial plasma in the Early Universe. We compute the number density at time of freeze-…
CP Violation in the SUSY Seesaw: Leptogenesis and Low Energy
Sacha Davidson, Julia Garayoa, Federica Palorini +1
We suppose that the baryon asymmetry is produced by thermal leptogenesis (with flavour effects), at temperatures GeV, in the supersymmetric seesaw with univ…
Insensitivity of flavoured leptogenesis to low energy CP violation
Sacha Davidson, Julia Garayoa, Federica Palorini +1
If the baryon asymmetry of the Universe is produced by leptogenesis, CP violation is required in the lepton sector. In the seesaw extension of the Standard Model with three hierarc…
Various definitions of Minimal Flavour Violation for Leptons
Sacha Davidson, Federica Palorini
Neutrino masses imply the violation of lepton flavour and new physics beyond the Standard Model. However, flavour change has only been observed in oscillations. In analogy with the…
