Description
- Present circumstantial evidences that seem to favour a scenario of baryogenesis via
leptogenesis from heavy particle decays - New experimental results that could further support this picture in the next future
- Difficulties for going beyond the level of "circumstantial evidences in favour...".
General no-go arguments forbidding leptogenesis scales sufficiently low to be directly
accessible in laboratory experiments. - Conditions and loopholes that might allow to circumvent the previous arguments for
building low scale leptogenesis models
Summary
I will review some features of leptogenesis from the decays of heavy particles.
After recalling the most appealing theoretical aspects, I will address the issue
of the main limitations and difficulties for experimental verification. I will then
describe some of the hardest challenges for constructing leptogenesis models
at low scales.
