Neutrino masses and Baryogenesis via Leptogenesis in the Exceptional Supersymmetric Standard Model
… asymmetry of universe problem and is called leptogenesis. However, one finds that in order to generated enough baryon number in the universe, the reheating temperature, which is required to be of order of the lightest right-handed neutrino mass, has to be higher than ∼ 10^9 GeV. The high …

SUSY Seesaw model and phenomenological implications for leptonic processes at low energies and leptogenesis
… on low-energy leptonic observables and thermal leptogenesis have been systematically investigated. Precision measurements will increase the sensitivity on lepton-flavor violating decays, particularly on Br(l_j->l_i gamma) and also on electric and magnetic dipole moments in the near future. In …

CP violation in the grimus-neufeld model /
… application of Grimus-Neufeld model to models of leptogenesis – a cosmological scenario, where matter-antimatter imbalance in the early Universe was created due to CP violating decays of heavy sterile neutrino. The goal of our work is to evaluate CP violation in the decays of Majorana neutrinos …

Thermal particle production in the early universe
… neutrinos, relevant for models of thermal leptogenesis, is computed to leading order in the SU(2) and U(1) gauge couplings and numerical results for the production rate are shown. Scattering processes involving top quarks and electroweak gauge bosons are additionally taken into account. …

Left-right symmetric model and its TeV-scale phenomenology
… electric dipole moments of charged leptons, and leptogenesis.

Neutrino Factory Targets and the MICE Beam
… seen in the universe, through the mechanism of leptogenesis. The Neutrino Factory will be a large international multi-billion dollar experiment combining novel new accelerator and long-baseline detector technology. Arguably the most important and costly features of this facility are the proton …

Polarisierte Photon- und geflavourte Lepton-Quantenboltzmanngleichungen im frühen Universum
Polarisation and Nongaussianity are expected to play a central role in future studies of the cosmic microwave background radiation. Polarisation can be split into a divergence-like E-mode and a curl-like B-mode, of which the later can only be induced by primordial gravitational waves (tensor …
