====== Leptogenesis ======
 

<tabbox Intuitive> 

The basic idea of Leptogenesis is that the baryon-antibaryon asymmetry that we observe was produced through a lepton-antilepton asymmetry. This asymmetry, in turn, was produced, for example, through the decay of right-handed neutrinos. 

The lepton asymmetry gets converted into a baryon asymmetry through vacuum tunneling processes known as [[advanced_notions:quantum_field_theory:sphalerons|sphalerons]].

<tabbox Abstract> 

<note tip>
The motto in this section is: //the higher the level of abstraction, the better//.

<tabbox Why is it interesting?> 
Leptogenesis is a possible solution for the [[open_problems:baryon_asymmetry|baryon asymmetry problem]] of the standard model.
