R-Parity Violation Axiogenesis / Co, Raymond T. (Minnesota U., Theor. Phys. Inst.) ; Harigaya, Keisuke (CERN ; Princeton, Inst. Advanced Study) ; Johnson, Zachary ; Pierce, Aaron
We show that the rotation of the QCD axion field, aided by $B-L$ violation from supersymmetric $R$-parity violating couplings, can yield the observed baryon abundance. [...]

Dept. ; Cambridge U., DAMTP) ; Simonović, Marko (CERN) ; Zaldarriaga, Matias (Princeton, Inst. Advanced Study) ; Nishimichi, Takahiro (Kyoto U., Yukawa Inst., Kyoto ; Tokyo U., IPMU) ; Takada, Masahiro (Tokyo U., IPMU)
Non-linear redshift-space distortions ("fingers of God") are challenging to model analytically, a fact that limits the applicability of perturbation theory in redshift space as compared to real space. [...]
