The abstract, sentence by sentence

arXiv listing abstract v3. Results and the main claim are underlined; show every role.

We present a mechanism to generate the baryon asymmetry of the Universe which preserves the net baryon number created in the Big Bang. If dark matter particles carry baryon number $B_X$, and $\sigma^{\rm annih}_{\bar{X}} < \sigma^{\rm annih}_{X} $, the $\bar{X}$'s freeze out at a higher temperature and have a larger relic density than $X$'s. If $m_X \lsi 4.5 B_X $GeV and the annihilation cross sections differ by $\gsi 10%$, this type of scenario naturally explains the observed $\Omega_{DM} \approx 5 \Omega_b$.

Asymmetric Dark Matter from Leptogenesis
hep-ph 2011-01 conditional novelty 6.0 of 10

Coupling the same right-handed neutrinos to the Standard Model and to a hidden sector generates the lepton and dark matter asymmetries together, allowing asymmetric dark matter masses spanning roughly 10 keV to 10 TeV.
Aidnogenesis via Leptogenesis and Dark Sphalerons
hep-ph 2010-09 conditional novelty 6.0 of 10

A shared non-abelian gauge symmetry generates dark sphalerons that convert a lepton asymmetry into both baryon and dark matter asymmetries, predicting a dark matter mass of about 6 GeV.
Asymmetric WIMP dark matter
hep-ph 2011-03 accept novelty 5.0 of 10

A primordial dark matter asymmetry combined with an ordinary weak-scale annihilation cross section yields a present-day population that is only partially asymmetric, filling the gap between thermal WIMPs and fully asy...
Asymmetric Sneutrino Dark Matter and the Omega(b)/Omega(DM) Puzzle
hep-ph 2004-10 conditional novelty 5.0 of 10

In a variant of the MSSM with mixed sneutrinos, the sneutrino asymmetry is fixed at one-third to one-sixth of the baryon asymmetry, naturally giving a dark matter density comparable to the baryon density.
Asymmetric Dark Matter and Dark Radiation

A dark sector with light dark radiation and heavier states that heat it produces a calculable extra relativistic energy density, and dark matter scattering off that radiation leaves a measurable imprint on the matter ...
