The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; show every role.

We investigate the possibility of low-scale leptogenesis in the minimal supersymmetric standard model extended with right handed (s)neutrinos. We demonstrate that successful leptogenesis can be easily achieved at a scale as low as ~ TeV where lepton number and CP violation comes from soft supersymmetry breaking terms. The scenario is shown to be compatible with neutrino masses data.

We investigate the possibility of low-scale leptogenesis in the minimal supersymmetric standard model extended with right handed (s)neutrinos. We demonstrate that successful leptogenesis can be easily achieved at a scale as low as ~ TeV where lepton number and CP violation comes from soft supersymmetry breaking terms. The scenario is shown to be compatible with neutrino masses data.

Fingerprint of Low-Scale Leptogenesis in the Primordial Gravitational-Wave Spectrum
hep-ph 2020-04 conditional novelty 6.0 of 10

Summing all harmonic modes of cosmic-string loops, the gravitational-wave spectrum breaks from a flat plateau to a minus-one-third slope, and in the minimal gauged B-L model that break encodes the right-handed neutrino mass.
Scalar Multiplet Dark Matter
hep-ph 2009-03 conditional novelty 5.0 of 10

Including scalar quartic couplings turns the single dark matter mass predicted by pure gauge annihilation into a range of allowed masses for SU(2) multiplets up to the 7-plet, with corresponding direct and indirect de...
Leptogenesis: beyond the minimal type I seesaw scenario
hep-ph 2012-12 accept novelty 2.0 of 10

Leptogenesis can be successfully implemented not only with right-handed neutrinos but also with scalar triplets, fermion triplets, and mixed seesaw sectors, each with its own CP asymmetry, efficiency, and lower mass bound.
Bounds on neutrino masses from baryogenesis in thermal and non-thermal scenarios
hep-ph 2006-02 conditional novelty 2.0 of 10

The thesis derives leptogenesis constraints on right-handed neutrino masses and mass hierarchies, and finds that decaying B-L cosmic string loops can produce the observed baryon asymmetry for symmetry breaking scales ...
