Renormalisation Group Invariants from Scaling and Non-overlapping Symmetries
Apostolos Pilaftsis
We show how the synergy of scaling and non-overlapping global symmetries can lead to Renormalisation Group Invariants (RGIs) among the parameters of potentials with multiple scalar…
Trajectories of Critical Unstable Qubits in and on the Bloch Sphere
Snehit Panghal, Apostolos Pilaftsis
We extend previous studies on a novel class of unstable two-level systems which were called Critical Unstable Qubits (CUQs). In an appropriately defined co-decaying frame, the CUQs…
Low-Scale Leptogenesis from Resonant Thermal Lepton Flavour Coherences
Shao-Ping Li, Apostolos Pilaftsis
Resonant heavy-neutrino mixing and sterile neutrino oscillations are two prominent mechanisms to realize low-scale leptogenesis, with singlet neutrino masses below TeV energies tha…
Critical Unstable Qubits in Particle Physics
Dimitrios Karamitros, Thomas McKelvey, Snehit Panghal +1
We study in detail the dynamics of unstable two-level quantum systems by adopting the Bloch-vector representation. We identify a novel class of critical scenarios in which the so-c…
Dominant Thermal Resonant Mechanism for Low-Scale Leptogenesis
Shao-Ping Li, Apostolos Pilaftsis
We explicitly demonstrate the importance of a new thermal resonant channel in the context of low-scale leptogenesis, which goes beyond the well-known mixing and oscillation of mass…
Leptogenesis and the relativistic degrees of freedom of the plasma
Dimitrios Karamitros, Thomas McKelvey, Apostolos Pilaftsis
We investigate the impact of the temperature dependence of the relativistic degrees of freedom (dofs) of the plasma on lepton and baryon asymmetry. Motivated by the significant eff…
