We study the quantum kinetic equations both analytically, via a perturbative expansion up to third order in the mixing angles, and numerically. The analytical solution allows us to identify the relevant CP invariants, and simplifies the exploration of the parameter space. We find that sizeable lepton asymmetries are compatible with non-degenerate neutrino masses and measurable active-sterile mixings.", optnote="WOS:000363555500002", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=2425), last updated on Fri, 13 Nov 2015 12:59:02 +0000", issn="1029-8479", doi="10.1007/JHEP10(2015)067", opturl="http://arxiv.org/abs/1508.03676", opturl="https://doi.org/10.1007/JHEP10(2015)067", archivePrefix="arXiv", eprint="1508.03676", language="English" }
